Quantum Leap is an American science-fiction television series created by Donald P. Bellisario, that originally aired on NBC for five seasons, from March 25, 1989 through May 5, 1993. It starred Scott Bakula as Dr. Sam Beckett, a physicist who leaps through spacetime during an experiment in time travel, by temporarily taking the place of other people to correct historical mistakes. Dean Stockwell co-stars as Admiral Al Calavicci, Sam's womanizing, cigar-smoking companion and best friend, who appears to him as a hologram.

Quantum Leap follows the story of Dr. Sam Beckett (Bakula), a physicist who has become stuck in the past as a result of a time-travel experiment gone wrong, and his attempts to return to his present, the late 20th century, by altering events in the past for the better, with the aid of a hologram of his friend Admiral Al Calavicci (Stockwell), monitoring him from Sam's present.
In the series premiere, Sam has theorized the ability to travel in one's own lifetime and is the lead scientist of the government-funded Project Quantum Leap, operating from a secret laboratory in New Mexico; Al oversees the project for the government. When Al learns that funding for the project is in danger of being pulled because no demonstrable results have come from the project, Sam takes it upon himself to step into the Quantum Leap accelerator to prove that the project works; unfortunately, he does this well before the project is ready to be demonstrated, and is sent into the past. When Sam gains consciousness, he finds himself suffering from partial amnesia, and is more surprised to find that his appearance to others, including what he sees in the mirror, is not his own face. He finds that Al has come to his aid as a hologram that only Sam can see and hear, as it is tuned to his brainwaves. Al, working with the project's artificial intelligence Ziggy (voiced by Deborah Pratt), determines that Sam must alter an event in the current period he is in so as to re-engage the Quantum Leap process and return home. Al helps Sam overcome some facets of his "Swiss-cheese memory" and provides information on history as it originally happened. He also updates Sam on future events and relates possible outcome-probabilities using a handheld communication device in contact with Ziggy. The device is often temperamental and must be struck a few times as it emits electronic beeping and whirring sounds before the information is revealed. With Al and Ziggy's help, Sam is able to successfully change history, and then leaps out, only to find himself in the life of someone else in a different period of time.
Episodes in the series subsequently follow Sam's reaction to each leap (typically ending the cold open with him uttering "Oh, boy!" on discovering his situation), and then working with Al and Ziggy to figure out his new identity and who he needs to help to "set right what once went wrong" and trigger the next leap. An episode typically ends as a cliffhanger, showing the first few moments of Sam's next leap (along with him again uttering "Oh, boy!" on discovering his situation), which is repeated in the following episode's cold open. Though initially Sam's leaping is believed by Al and the others on the Quantum Leap team to be random, the characters come to believe in later seasons that someone or something is controlling Sam's leaping, and this is a central focus of the show's finale episode, "Mirror Image".
When Sam leaps, his body is physically present in the past, although he appears to others as the person into whom he leaped. In one case, after leaping into a Vietnam veteran who has lost both legs, Sam is still able to walk normally, but appears to others as if he is floating. Sam's body and mind may become jumbled with those into whom he has leaped. In one situation, he leaps into a woman near the end of her pregnancy and feels her birth pains, while in another episode, he leaps into Lee Harvey Oswald and feels an intense pressure to assassinate John F. Kennedy, despite knowing that it is the wrong thing to do. Similarly, the persons into whom Sam has leaped are brought into the future, where they appear as Sam to the others; they are normally kept in an isolated waiting room to prevent them from learning anything about the future, and they return to their own time when Sam leaps.
In most of Sam's leaps, the changes he makes are small on the grand scale, such as saving the life of a person who might otherwise have died, or helping making someone's life better. Selected episodes, however, demonstrate more dramatic effects of his time travels. In one episode, Sam's actions ultimately lead to Al's death prior to the project, and Sam finds himself suddenly aided by a new hologram, "Edward St. John V" (played by Roddy McDowall), and must work to prevent Al's death. In another episode, when again the project's funding is threatened, Sam helps a young woman successfully pass the bar; this results in her becoming one of the members of Congress who oversees the project and aids in the restoration of its funding. In the episode involving Lee Harvey Oswald, while Sam and Al do not prevent the assassination of Kennedy, Sam's actions prevent Oswald from making a second shot that killed Jacqueline Kennedy in the fictitious original history.
Because of the time-travel aspect, many episodes allude to famous people or incidents indirectly, such as Sam suggesting to young Donald Trump that New York real estate will be valuable in the future, suggesting the lyrics of "Peggy Sue" to a teenaged Buddy Holly, showing young Michael Jackson his signature moonwalk dance for the first time, giving Dr. Henry Heimlich the idea for his namesake maneuver by saving him from choking, and setting in place actions that lead to the discovery of the Watergate scandal. Two notable episodes place Sam directly at the center of significant historical events, one being the leap into Oswald. In "Goodbye Norma Jean", Sam appears as Marilyn Monroe's bodyguard, who saves her life and convinces Marilyn to remain alive for her starring role in The Misfits. Other episodes explore the past of the main characters, such as Sam saving his brother from being killed in the Vietnam War, and saving Al's marriage to Beth.
In the final episode, "Mirror Image", Sam leaps through spacetime as himself (without replacing another person), arriving at the exact time of his birth, where he meets a mysterious barkeep (Bruce McGill, who also appeared in the first episode in a different role). The barkeep is aware of Sam's situation and assures him that Sam himself controls the very nature and destinations of his leaps ("to make the world a better place"), and that Sam is always able to return home.
Cast and characters
- Dr. Samuel "Sam" Beckett (played by Scott Bakula, who also narrates the episodes in character) is a quantum physicist with six doctoral degrees. He grew up on his parents' farm in Elk Ridge, Indiana, with an older brother (Tom) and a younger sister (Katie). Sam's idol is Albert Einstein.
- Albert "Al" Calavicci, USN (played by Dean Stockwell) is a womanizing U.S. Navy rear admiral and Sam's best friend, who grew up in an orphanage and was later active in the Civil Rights Movement. At the time of Sam's leaps, Al spends his free time with his lover and the project's medical technician Tina Martinez (played by Gigi Rice), who appears in the fourth-season episode "The Leap Back".
- Ziggy (voiced by the introduction narrator, Deborah Pratt, who was also a co-executive producer of the show) is the self-aware artificial intelligence "parallel hybrid computer with an ego" that runs Project Quantum Leap, and helps Sam throughout his leaps, and appearing in the fourth-season episode "The Leap Back."
- Irving "Gooshie" Gushman (played by Dennis Wolfberg) is the project's often-mentioned head programmer, who is said to have bad breath. He appears in five episodes, including the pilot and the finale.
- Dr. Verbena Beeks (played by Candy Ann Brown) is often mentioned as the project's psychiatrist. She appears in two episodes throughout the series.
In each episode, a different cast of guest characters appears, mostly the ones whom Sam replaces with his leaps. Several other characters are referred to regularly throughout the series, but are mostly unseen.
The main premise for Quantum Leap was inspired by such movies as Heaven Can Wait and Here Comes Mr. Jordan. It also may have evolved out of an unused Battlestar Galactica story that was proposed for the Galactica 1980 series. Series creator Donald P. Bellisario saw its concept as a way of developing an original anthology series, as anthologies were unpopular with the networks.
The theme for the series was written by Mike Post. It was later rearranged for the fifth season, except for the series finale episode, which featured the original theme music. Scores for the episodes were composed by Post and Velton Ray Bunch.
A soundtrack album was first released in 1993, titled Music from the Television Series 'Quantum Leap' , dedicated to John Anderson, who played Pat Knight in The Last Gunfighter. It was released by GNP Crescendo on CD and cassette tape.

The most frequent time slot for the series is indicated by italics:
- Sunday at 9:00–11:00 pm on NBC: March 26, 1989

In the United Kingdom, the show began on BBC Two on February 13, 1990 , airing Tuesday evenings at 9:00 pm. The final episode was scheduled to be aired on June 14, 1994, but altered schedules after the death of British dramatist Dennis Potter earlier that month delayed the airing until June 21, 1994.. Repeat episodes continued on the channel at various times until December 28, 1999 . It has since aired several times on satellite and cable television, rerunning late at night on television channel Cozi TV.
Universal Studios Home Entertainment has released the entire, digitally remastered, Quantum Leap series on DVD. Some controversy arose when fans discovered that many songs had been replaced from the soundtrack due to music rights issues. For the fifth season, Universal included all of the original music.  
On February 7, 2017, Mill Creek re-released Quantum Leap - the Complete Series on DVD and also released the complete series on Blu-ray for the first time. The 18-disc set contains all 97 episodes of the series, as well as most of the original music restored for all seasons.

At the end of season five, Bellisario was told to write an episode that could serve as a season finale or series finale, as whether Quantum Leap would be renewed was unclear. The episode contained some answers to long-standing questions about the show, but contained enough ambiguity for a season six. However, when the show was not renewed, two screenshots were tacked on to the end of the last episode; one read that Al’s first wife Beth never remarried, so they were still married in present day and had four daughters. The last screenshot said Sam never returned home. The finale was met by viewers with mixed feelings.
A few years after the airing of the finale, a script for an alternate ending was leaked on the internet. It implied that Al, through encouragement of his wife Beth, would become a leaper to go after Sam and that they would be leaping into the future. Bellissario has said no script exists and that he does not know where this idea came from. However in 2018, fan Allison Pregler purchased screen shots taken from season five that contained some shots of Al and Beth together; this implies that part of the alternate ending was, in fact, shot and gives credibility to the alternate-ending scenario. In May 2019, a video of the lost footage was actually uploaded to Reddit by a contributor with the handle Leaper1953. How this person obtained the footage is not known publicly. Scott Bakula confirmed that several endings were shot and that the footage was authentic.
Despite its struggling start with poor broadcast times, the series had gained a large 18–49 demographics of viewers. The finale was viewed by 13 million American households. In 2004 and 2007, Quantum Leap was ranked number 15 and 19, respectively, on TV Guide's "Top Cult Shows Ever".

Few of the comic stories referenced episodes of the television series, with the exception of the ninth issue, "Up Against a Stonewall".
Occasional announcements of plans to revisit or restart the series have been made. In July 2002, the Sci-Fi Channel announced its development of a two-hour television film based on Quantum Leap, which it was airing in reruns at the time, that would have served as a backdoor pilot for a possible new series, with Bellisario as executive producer. During the TV Guide panel at the 2010 San Diego Comic-Con International, Scott Bakula said that Bellisario was working on a script for a projected Quantum Leap feature film. In October 2017, Bellisario confirmed at the L.A. Comic Con that he has finished a script for a feature film.
In popular culture
Adult Swim's Robot Chicken has parodied the show on at least two occasions, once showing the character of Sam Beckett leaping into a woman who appeared to be a sex worker. On another episode, a character is shown 'leaping' into other characters and his reflection is not his own. This episode also features an opening theme similar to Quantum Leap.
Seth McFarlane's Family Guy has referenced the show on at least three different episodes. In "The Father, the Son, and the Holy Fonz", Peter Griffin is shown going door-to-door as a Jehovah's witness and says that Jesus, "would travel from place to place putting things right that once went wrong, and hoping each time that his next leap would be the leap home"; then the show cuts away to an animated Jesus 'leaping' into a scene. In "The Kiss Seen Around the World", Al the hologram is shown entering a scene as he would on Quantum Leap and character Neil Goldman asks, "Al, why haven't I leaped?" In the episode "Back to the Pilot", Stewie says he learned the rules of time travel by watching the show.
On June 16, 2016, Scott Bakula made a brief reprise of his role as Sam Beckett on The Late Show with Stephen Colbert. Colbert made a reference to an episode where Sam Beckett has leapt into the body of a 1950s New York cab driver, whose comment about investing in New York real estate is heard by a young Donald Trump. Using a handset to talk to Ziggy, Colbert leaps back as a hologram to help Sam Beckett attempt to change the future.
