Alan Shore (played by James Spader, The Practice, Season 8, 2003–2004; Boston Legal, Seasons 1–5, 2004–2008): A brilliant lawyer with a strong moral core who nevertheless is not above obtaining ethical outcomes through unethical means. Illicit computer hacking, blackmail, disguise and bribery are all tools he uses without hesitation. Alan is, however, unwavering in his defense of the underdog (unless he is representing the other party) and an indefatigable patron of various left-wing causes. He is disappointed and disillusioned with how the country has changed in recent years, and routinely confronts these issues in open court. Wherever he works, he treats his coworkers with levity and refuses to take himself too seriously. Alan suffers from night terrors, has a fear of clowns and, in two episodes, suffered from word salad. He has resigned himself to the fact that he will never be made partner at the firm due to his unpredictable behavior and lack of trustworthiness. While the managing partners of Crane, Poole & Schmidt do not fully trust Alan, they do recognize his talent as an attorney and will often give him the latitude to go about his unorthodox means if they feel it will benefit the firm. Alan is best friends with Denny Crane despite their sharp differences in political ideologies. He is also a womanizer and was married in the past, his wife having since died. He convinces Chang to keep the litigation team on the payroll at CP&S, "Shirley Schmidt, Denny Crane, Carl Sack, Jerry Espenson, Katie Lloyd, me. We run the show."
Shirley Schmidt (played by Candice Bergen, Seasons 1–5, 2004–2008): Founding and Senior Partner of Crane, Poole & Schmidt. Shirley first appeared in the middle of the first season. She attended Wellesley College where she met her share of intelligent Harvard students. Shirley used to have a romantic relationship with Denny, a past she now views with sardonic detachment, often making jokes about it. She is portrayed as extremely desirable in the series: smart, sexy, and sought after by many of the men around her, including her ex-husband Ivan Tiggs and fellow lawyers Denny, Alan, Jeffrey Coho and Carl Sack. She eventually marries Carl in the series finale.
Denny Crane (played by William Shatner, The Practice 2004, Season 8; Boston Legal, Seasons 1–5, 2004–2008): Founding and Senior Partner of Crane, Poole & Schmidt, Denny is a renowned attorney of some fifty years of practice who claims he has never lost a case, and never will. He considers himself a legend and loves to say his own name to "sign" his verbal utterances. In one of the final episodes of The Practice, he explained that often people don't believe they're in the room with a legend, so he says his own name to let them know it's true. Denny often refers to a condition he calls "mad cow" when his utterances are confusing to others or when he himself becomes confused. While there are instances of Prion diseases in humans, it is much more likely that Denny is suffering the early stages of Alzheimer's or another form of dementia. While he is still trying cases as late as Season 1 of Boston Legal, by Season 2, he seems to have lost most of his talent for complex litigation, though he still shows flair in appealing to a jury in closing arguments. He is a conservative who believes gun control is for "communists" and refuses to defend anyone who is accused of extremely heinous acts; in one episode, he shoots a client because of the nature of his crime (raping and murdering a child). Denny is also a womanizer, and has no problem sleeping with the wives of judges and clients. Though he marries another woman in Season 2 (from whom he is quickly divorced after engaging in an act of infidelity at their wedding reception), he still pines for Shirley Schmidt.
Carl Sack (played by John Larroquette, Seasons 4-5, 2007–2008): A senior partner at Crane, Poole & Schmidt, Carl transferred from the New York office to help Shirley in managing the Boston branch following the withdrawal of Paul Lewiston from a leadership role to concentrate on raising his granddaughter. He is initially unable to come to terms with the carefree conduct of the Boston office and once considers moving back to New York. However, he finds his footing in the Boston office, becoming a mentor to the associates, particularly Katie Lloyd, Clarence Bell and Jerry Espenson. He also falls in with the sometimes surreal legal activities of the Litigation Division, notably by filing a lawsuit against the broadcast television networks in which the plaintiffs demanded that they air programs for people with working brains. Carl is an old flame of Shirley's and proposes to her in "Thanksgiving." Shirley and Carl are married in a civil ceremony by Supreme Court Justice Antonin Scalia at Nimmo Bay in the series finale.
Jerry Espenson (played by Christian Clemenson, Seasons 2-5, 2005–2008): An attorney diagnosed with Asperger's syndrome, although his quirks seem to be a misrepresentation of the syndrome, being closer to Tourette's Syndrome than Asperger's. These quirks include purring whenever he feels anxious and upset; constantly exclaiming "Bingo!" as an affirmative; hopping when excited; and awkwardly walking with his hands pressed to his thighs (which earned him the moniker "Hands Espenson" among the other CP&S attorneys). Since his diagnosis, Jerry has received mental and behavior modification therapy which has increased his confidence in dealing with people. Before his disorder was diagnosed, he was arrested for holding a knife to Shirley's throat after being denied partnership in the firm for the third time. Shirley dropped the charges against him after Alan promised to get Jerry the therapy he needed. After therapy, he founded his own successful law firm and opposed Alan Shore in a few cases, beating him in court despite Alan's employment of various tricks intended to rattle him. Jerry was able to use his firm and its client list as levers to rejoin CP&S, moving from the Corporate Law department to Litigation, where he was surprisingly successful, to the delight of Alan and Shirley. He made partner in the final season, following a declaration of support from Denny Crane and an eloquent speech of his own to the partners. Carl Sack, who had initially been dubious about him, was proud to extend the offer of partnership in the firm to Jerry.
Katie Lloyd (played by Tara Summers, Seasons 4-5, 2007–2008): A young British attorney hired by Shirley, and assigned by Carl to share an office with Jerry. A talented and moralistic young woman, able to see the good in people that others cannot, Katie becomes best friends with Jerry, helping him with his behavioral issues caused by his Asperger's Syndrome. She is rather surprised at how fiercely protective of her Jerry can be. As Jerry comes to understand more of social behaviors, the two eventually begin to date and were asked to be present at Carl and Shirley's wedding. In their last onscreen appearance, they kiss outside Katie's apartment house, with the implication they are now an item.
Paul Lewiston (played by Rene Auberjonois, Seasons 1–3, 2004–2006 guest app. Season 4, 2007, Season 5, 2008): Managing Partner of the Boston office and legal advisor of Crane, Poole & Schmidt. Paul is skilled in client relations and is an expert in Far Eastern markets and legal problems of corporations doing business in that part of the world. Unlike Denny and Alan, Paul generally does things strictly "by the book." He has had several antagonistic run-ins with Denny and Alan over their apparent lack of respect for the law. His middle-aged daughter, Rachel, is introduced in Season 2 as a meth addict, and Paul has her abducted and placed in a rehab center. He takes custody of her daughter (and his granddaughter) Fiona. After this, being tied up with being a daddy to his grandchild he is seldom seen in the Boston office. It was Lewiston who negotiated the acquisition of Crane, Poole & Schmidt by a Communist Chinese law firm, not realizing until the very end of the process that he had played the role of Judas Iscariot to the law firm he had helped to build into a name respected around the world.
Brad Chase (played by Mark Valley, Seasons 1-3, 2004–2006, guest app. Season 4, 2007): The man who the others turn to when they need something done, relying on his Marine Corps background to intimidate others. Brad helped Denise rescue a kidnapped child by extracting information from a priest, accidentally chopping off the priest's fingers in the process. Later, he went undercover to discover if Paul Lewiston's daughter was still using meth. Brad hated Alan initially, but later became slightly more tolerant of him. He was made a partner in Season 2. In Season 3, he has a relationship with Denise that evolves from "friends with benefits" to marriage. After Denise becomes pregnant, he leaves the firm to become a district attorney. Brad and Denise are married moments before the birth of their daughter by Judge Robert "Poopycock" Sanders.
Denise Bauer (played by Julie Bowen, Seasons 2-3, 2005–2006, guest app. Season 5, 2008): An aggressive young attorney introduced at the start of Season 2, Denise is thrown when her husband files for divorce and insists that she pay him so he can live while setting up his career as a mediocre golf pro. Her distractions over the divorce cause her trouble with some cases. In episode 14 of the third season, Denise discovers she is pregnant, and as of the seventeenth episode, she had decided to have the baby. After discovering that A) the baby is Brad Chase's, and B) that she is in love with him, she plans a big church wedding and goes into labor while she is going down the aisle. Brad and Denise are married moments before the birth of their daughter by Judge Robert "Poopycock" Sanders. She leaves Crane, Poole & Schmidt after her maternity leave, and becomes a partner in a different law firm. In that role, she subsequently crosses swords with Alan Shore in the courtroom.
Lori Colson (played by Monica Potter, Season 1, 2004–2005, guest appearance Season 2, 2005): A junior partner at Crane, Poole & Schmidt and former prosecutor. Lori found herself inexplicably attracted to Alan during the first season. Late in the first season, she nearly filed a sexual harassment claim against Denny. Lori has since left the firm, either under pressure from or fired by Shirley.
Tara Wilson (played by Rhona Mitra, Season 1, 2004–2005, guest appearance Season 2, 2005): A paralegal at Young, Frutt & Berlutti, she graduated from law school in time to go with Alan to Crane, Poole & Schmidt. After a long flirtation on both The Practice and the half of the first season of Boston Legal, Tara and Alan finally began a sexual relationship, but the arrival of an old boyfriend led her to break up with Alan and quit the firm.
Sally Heep (played by Lake Bell, Season 1, 2004, guest appearance Season 3, 2006): An associate at Crane, Poole & Schmidt. First introduced in The Practice, Sally began a relationship with Alan that crossed over into Boston Legal. However, after he used her to get information from a witness against their client so they could suppress his testimony, she broke up with him. Shortly after Shirley took over the Boston offices, she fired Sally for repeated errors in case preparation that called her competence as a lawyer into question. Sally returns in Season three as opposing counsel (“Whose God Is It Anyway?” and “The Verdict”). This appearance addresses her transformation from an insecure junior to an assertive and sexually exploitive character.
Sara Holt (played by Ryan Michelle Bathe, Season 2, 2005–2006): Introduced in the second season premiere, Sara is a smart lawyer who isn't above using her own beauty to help her client. A first year associate, she is not seen again after the end of Season 2. It is unclear whether she is still with the firm or was let go by the partners.
Garrett Wells (played by Justin Mentell, Season 2, 2005–2006): Also introduced in the second season premiere, Garrett is a brash young attorney who is obviously attracted to Denise. He does go over her head with some clients but aids her by blackmailing her ex-husband's attorney/pastor to get him to back down from his demands for money. He is not all that effective in the courtroom, being humiliated on more than one occasion by no-nonsense judges. He is also intimidated by Catherine Piper, the caterer and former assistant to Alan Shore, who actually runs him out of his own office. He is not seen after the end of Season 2. It is unclear whether he is still with the firm or was let go by the partners.
Jeffrey Coho (played by Craig Bierko, Season 3, 2006): An intense, grandiose criminal defense attorney from the New York branch of Crane, Poole & Schmidt who joins the Boston firm in Season 3, accompanied by Claire Simms. Jeffrey is as comfortable with making enemies as he is making friends. He had a fleeting relationship with Denise, and as such is cordially despised by Brad Chase. After finding out that Denise's baby is not his, Jeffrey leaves the firm in episode 15 of Season 3 wearing his Buzz Lightyear costume.
Claire Simms (played by Constance Zimmer, Season 3, 2006): A smart, sexy lawyer who, along with Jeffrey Coho, joins the firm in the second episode of Season 3. She did undercover work in the Scott Little case, and has a penchant for flirting with witnesses. Claire initiated a relationship with Clarence Bell, who was first her assistant and later a fellow associate. She was written out following the end of Season 3, absent any explanation.
Clarence Bell (play by Gary Anthony Williams, Seasons 3-4, 2006–2007): Also known as Clarice, Clevant and "Oprah." In his default persona, Clarence is hopelessly shy and introverted. To deal with this drawback, he role-plays as other people who embody the characteristics he cannot. He originally sued his place of employment for gender discrimination. He is hired by CP&S as Claire Simms' assistant, and after it is discovered he is a law school graduate who has been admitted to the bar, he becomes an associate. For a time, he and Claire are an item. Joining the Litigation Division, he and Jerry Espenson become friends, and he enjoys something of a mentoring relationship with Carl Sack. He disappeared at the end of Season 4 with no explanation.
Lorraine Weller (played by Saffron Burrows, Season 4, 2007–2008). An Englishwoman by birth, Lorraine came to America as a result of an agreement with the British government. She had been a high class madam in London, with a string of escorts who serviced very senior members of the British government (and, it was rumored, the Royal Family). Her current citizenship is unclear, though it may be presumed she is a naturalized American. She graduated from Harvard Law School and was admitted to the Massachusetts bar. Joining Crane Poole & Schmitt as a litigator, her background is discovered by Whitney Rome and Katie Lloyd -- who also discovers, following Jerry's losing his virginity to an escort who had fallen for him, that Lorraine is still a practitioner of "the oldest profession," running strings of high-priced escorts in Boston, New York, and Washington, DC. Shortly after this information became known at the firm, Lorraine left Crane, Poole & Schmidt. Whether she resigned or was fired is unclear.
Whitney Rome (played by Taraji P. Henson), Season 4, 2007–2008) A strong-willed associate who transferred to Crane, Poole & Schmidt’s New York offices after a break-up. In her arrival at the firm, Whitney is immediately thrown into a case involving a bullfighting child whose mother wants sole custody.
Bethany Horowitz (played by Meredith Eaton-Gilden): A feisty dwarf attorney, and an on-again-off-again romantic interest of Denny. Bethany is also the daughter of an old girlfriend of Denny's. At one point it was suspected Bethany was actually Denny's daughter, which theory was disproved by DNA tests. Bethany ultimately was unable to reconcile the fact her mother had had a relationship with Denny, plus the fact that she was a practicing Jew while Denny was (nominally) Christian, and the two parted for good.
Judge Robert Sanders (played by Shelley Berman): A crotchety old judge, who seems to be suffering from senility and utters comic-sounding phrases such as "jibber-jabber" and "poopycock." He also, in a jab by the writers at then-President George W. Bush, frequently claims to be "the decider." Judge Sanders can be manipulated by attorneys, particularly Alan Shore. He also married Brad Chase and Denise Bauer in the labor room of a hospital after Denise went into labor at her wedding moments before the baby was born, because Brad insisted no child of his would come into the world a bastard.
Catherine Piper (played by Betty White): Alan's former assistant, first introduced in The Practice. A church-going woman who enjoyed being privy to the goings-on at Crane, Poole & Schmidt, Catherine took to the matricidal Bernard Ferrion in an attempt to introduce him to God. Convinced Ferrion would kill again, she later murdered him. With Alan's representation, Catherine was acquitted of the crime but was subsequently fired by Shirley. However, Catherine returned and was hired as a food delivery person at Crane, Poole & Schmidt. She was involved in other lawsuits concerning elder citizen rights, including a lawsuit brought by Carl Sack against the television networks that argued the networks had an obligation to present shows that met the needs of senior citizens with working brains. (This episode was a slap at ABC, which threatened to cancel Boston Legal repeatedly due to its declining 18-49 age group ratings, and moved it around the schedule at whim.)
Edwin Poole (played by Larry Miller): The third Named Partner at Crane, Poole & Schmidt. Edwin arrived at a partners meeting pantless and was sent to a psychiatric hospital in the first few minutes of the pilot. He later escaped, much to Denny's concern, and he successfully participated in one case before deciding to go back. He returned again for one episode in Season 2 after being released, focusing his efforts on finding someone to sue. Edwin returned to the hospital on Shirley's advice. He reappeared in the final season as the foster parent of a black boy and was present at the Thanksgiving Day dinner where Carl Sack asked Shirley to marry him and the possibility of the firm going under was discussed.
Marlene Stanger (played by Parker Posey, Seasons 2-3, 2005–2006): A stone-cold, ruthless attorney. Known at her old firm as "The Squid" (apparently the only animal that can kill a shark, a term commonly used to describe someone with aggressive ambition in the legal or corporate world), Marlene is not above using underhanded tactics to win cases, and specializes in undermining her associates. She finds herself very unnerved by Alan, and eventually had sex with him in his office. Her hostile relationship with Denise led to the ruining of Denise's chance to make partner. At the end of Season 2, in accordance with the contract by which she joined Crane, Poole & Schmidt Marlene was made a partner; but in the third season premiere, she transferred from Boston to the New York office.
Frank Ginsberg (played by Currie Graham): An assistant district attorney with political ambitions. He wants to get elected district attorney, and has tried to further this goal by promoting himself to the public with cases of questionable merit. Some instances of his misguided intentions include prosecuting a sexual surrogate and her patient (Jerry) for prostitution, trying to imprison a homeless man who cannibalized a dead body when death by starvation became imminent, and attempting to put Denny behind bars for illegally exporting medical waste. On each occasion, Ginsberg's plans to use his cases as sensational self-promotion were ruined (typically by Alan Shore) when his targets were acquitted.
Bernard Ferrion (played by Leslie Jordan): A short statured man, who whacked his mother over the head with a frying pan and proceeded to hire Alan as his lawyer. Bernard's mother dies shortly thereafter, but manages to tell about Bernard's act; however, Alan manages to acquit Bernard due to lack of evidence. Bernard's neighbor witnesses the killing, and for fear of incrimination, Bernard murders her in the same manner. He seeks Alan's help once more, but Alan deems him evil and turns him over to Tara, who also acquits him due to lack of evidence. Bernard keeps returning to Crane, Poole & Schmidt in unsuccessful attempts to regain his friendship with Alan, and befriends Catherine, who tries to "save his soul" by introducing him to religion. However, as Bernard keeps displaying signs of willingness to kill again just for the thrill and attention, Catherine starts to fear for her own life, and so kills Bernard in the same manner he killed his mother and neighbor, and hides his body in a freezer.
Lincoln Meyer (played by David Dean Bottrell): A campy eccentric, Meyer was a witness in the murder trial of his neighbor, a female judge on whom he had an unrequited crush. Meyer is a lonely peeping Tom, and is revealed to have developed psychosis, which causes him to sue anyone who calls out his eccentricity, and later cause physical harm to the point of murdering the judge who denied his motion, trying to murder a TV show hostess, and even kidnapping Shirley following her refusal to go out on a date. Meyer's house is eventually raided by the police following a hunch from the Crane, Poole & Schmidt partners and associates, and he is shot in the chest by his own crossbow, which he set up as a booby trap to prevent Shirley's rescue.
Daniel Post (played by Michael J. Fox): Denise's love interest with terminal lung cancer. Daniel is a hugely wealthy businessman who initially goes to Denise for help winning a case against a man who is suing him for using his influence to get a test drug that might save his life. Their relationship develops until he restarts his radiation therapy and then goes off to Europe, presumably to die. Daniel returns in the season finale, alive, and proposes to Denise. In the third season, he dies during a lung transplant, however, and his remains are lost on the black market. Denise was able to recover his head in a haunted house Halloween attraction in Salem, Massachusetts.
Chelina Hall (played by Kerry Washington): Prior to coming to work for Crane, Poole & Schmidt in Boston, Chelina worked on behalf of death row inmates for the Texas Innocence Project by petitioning the Texas High Court to reconsider execution sentence. She lost her temper during her final appearance before the court, calling the chief judge "a disgusting, fat pig." Later, when one of her previous cases comes up for appeal, Chelina fears this incident may have prejudiced the judge against her and convinces Alan to argue the case in her stead. She was originally intended to appear in several episodes near the end of the first season, but when these episodes were retooled to appear at the beginning of the second season, her burgeoning romance with Alan was apparently cut short. Alan re-encounters Chelina in the second season episode "Race Ipsa" (actually a holdover from season one) and in a comment that broke the fourth wall, Alan says that she has left the show "to be in movies" (which she did in real life), also making reference to the change in the show's airing time.
Donny Crane (played by Freddie Prinze, Jr.): A young lawyer who was believed to be Denny's illegitimate son, the product of an affair with an anonymous woman. Denny, however, did not see him for fifteen years. Denny later confessed to Alan that when Donny's mother slapped him with a paternity suit, he settled, and Donny's mother later admitted that he wasn't the father. Many jokes were made about the closeness of Donny and Denny's names. When Donny found out that Denny was not his biological father, he was crushed, and his relationship with Denny became very strained; however, Denny still considers him his son and has referred to him as such on occasion. Just like Denny, Donny uses his own name as an exclamation at inappropriate times.
Ivan Tiggs (played by Tom Selleck): Shirley Schmidt's ex-husband and a womanizer. After announcing his engagement to his sixth wife Missy, he attempted to rekindle his former relationship with Shirley, saying he would dump Missy if Shirley would take him back. When Shirley refused, he married Missy and later lied about leaving her to reunite with Shirley. The ploy worked, and he and Shirley were briefly reunited. When Shirley learned of his deception, she drafted a "post-nuptial agreement" that would relinquish virtually all of Ivan's possessions to Missy if he were ever caught cheating on her. He attempted to legally void the agreement (with Alan as his representation), but eventually handed everything over to Missy if Shirley would give him another chance. Shirley refused, saying "I can't love you anymore," and Ivan was last seen alone and penniless.
Missy Tiggs (played by Meredith Patterson): The eccentric, obnoxious, Broadway musical-loving, singing, snort-laughing, and very young sixth ex-wife of Ivan Tiggs. She is brought into court by a black man with whom she had protected sex, after Missy took his sperm from a condom and used it to impregnate herself with an "Obama baby." The black man brought suit against her, which case was resolved to the satisfaction of no one. It is unknown if Missy gave birth or not as she disappeared after that episode.
Judge Clark Brown (played by Henry Gibson): A 70 year-old judge who still lives with his mother, Judge Brown likes to humiliate criminals he convicts in addition to normal punishment. Although Judge Brown claims to be a "conscientious fact finder", both Alan and Denny are able to appeal to his insecurities to gain favorable rulings. Initially thought to be a virgin, Brown admitted to having relationships with men in the Season 3 episode "Selling Sickness." He also often utters strong adjectives like "Shocking!" or "Disgusting!" during witness testemony, and often describes things as "Outrageous!"
Melvin Palmer (played by Christopher Rich): A Texan lawyer and Alan's nemesis. He is extremely (but falsely) friendly and charming, and uses this as a strategy in nearly all his cases. Only once does he drop his facade, revealing him to be a cold, amoral and manipulative lawyer. Alan immediately despises him, and he occupies the role of an antagonist until near the end of the show, where he defends Denny and Alan from adultery charges. This leads to Melvin and Denny becoming good friends, which irritates Alan further.
