Hadleigh has an M.A. in journalism and has traveled to more than 60 countries. He has published 18 books and has written for more than 100 magazines in the U.S. and abroad, including TV Guide, Playboy, and Us Weekly. He won $16,400 as a contestant on the March 20, 1998 episode of the game show Jeopardy!
He lives in Beverly Hills, California and Sydney, New South Wales. His latest books are Broadway Babylon (2007), and Mexico's Most Wanted (2007). Hadleigh's books have been translated into 14 languages, and half of his first 16 books have been made into television specials and documentaries in the U.S., U.K., and elsewhere.
Several of his books deal with pop culture and/or entertainment history, and how the media and status quo shape and manipulate audiences' perceptions and opinions. Six of his eighteen books are exclusively about the LGBT presence in and contributions to entertainment; Hadleigh himself is gay. Some of Hadleigh's books are quotes collections, some are histories and overviews, and some are interview books with noted personalities in movies; several portions of these interviews, as with Rock Hudson, were published in periodicals before the subjects died. The author had committed himself not to out any of his subjects against their will — at least as long as they were living. Some interviewees agreed to speak only on condition that the published result be posthumous. Nearly all the interviews were recorded; a few individuals, like director Rainer Werner Fassbinder and Mae West, however, refused to speak if they were recorded—which was their policy with other interviewers as well.
Selected (and selective) reviews
Hadleigh's second book, Conversations With My Elders (republished as Celluloid Gaze) includes interviews with actors Sal Mineo and Rock Hudson; directors George Cukor, Luchino Visconti, Fassbinder, and designer, photographer/author Cecil Beaton.
Their frank conversations with the author reveal much about the lives and careers of these celebrities and how their homosexuality affected both. According to Midwest Book Review, the book "is a ground breaking collection of interviews with six men who share a common and unusual trait relevant to their success in the movie-making industry: they were gay, and during their lifetimes, they concealed their sexual orientation from the public. Yet these interviews are remarkably open and candid about how these men's sexuality affected their lives and careers. ... Celluloid Gaze is an informed and informative contribution to Film History and Gay Studies academic reference collections and supplemental reading lists, as well as highly recommended reading for fans of the film work of Sal Mineo, Luchino Visconti, Cecil Beaton, George Cukor, Rainer Werner Fassbinder, and Rock Hudson."
- Hollywood Gays is a collection of interviews with prominent film personalities, such as Liberace, Anthony Perkins, Randolph Scott, and several others, most of them widely known as homosexual. Publishers Weekly said about the book:
- Hadleigh (is) evidently taking up where the great gossip columnists of yesteryear left off.
- [A] touching interview with producer David Lewis, who talks freely about his longtime companion James Whale, director of the classic 1931 films Frankenstein and The Invisible Man, who committed suicide in 1957.
- [A] talk with William Haines, whose career was destroyed by Louis B. Mayer after Haines refused to marry a woman, and was later caught with another man in his cot at a YMCA. The book's style is suitably straightforward, though Hadleigh's banter often verges on the cute or leering.
- Hollywood Lesbians is a collection of frank, often revealing interviews with ten lesbians in the entertainment industry. Publishers Weekly wrote: "Fans of Hollywood's golden age will find this collection of interviews conducted over many years revealing, though hampered. The subjects - director Dorothy Arzner, designer Edith Head, actresses Judith Anderson, Marjorie Main, Barbara Stanwyck, Nancy Kulp, Capucine, Patsy Kelly, Agnes Moorehead and Sandy Dennis — were raised in a generation terrified of voicing support for fellow homosexuals, let alone daring to come out of the closet to acknowledge their own sexuality... Still, with carefully couched questions from Hadleigh (Conversations With My Elders), though some of the respondents dance around the subjects of sex and sexuality. Still, an enlightening picture emerges of Tinseltown, different from that presented in the fanzines.
- Hollywood Babble-On: Stars Gossip about other Stars (1994) includes dish and juicy comments by stars on other stars.
Questions of authenticity
Hadleigh's veracity concerning some source material has been questioned. Hadleigh claims that, in 1959, Time critic Richard Schickel's review of the film version of Williams' Suddenly, Last Summer, starring Elizabeth Taylor and Montgomery Clift, bemoaned: "Why do we have to have all of this homosexuality in our movies?" But Time spokeswoman Dawn Bridges says Schickel didn't start reviewing movies for Time until 1973, and the quote does not appear in the magazine at all.
"Time reviews didn't have bylines until the late 1960s, so it's not even possible that they could attribute it to Schickel if it ran. And I spoke to Richard, who said he never knew of any anti-Williams feelings by Luce . . . The quote and attributing it to Richard is just wrong."
Upon the publication of Conversations With My Elders, Publisher's Weekly wrote: "There's nothing very surprising about his choice of subjects — Paul Lynde, Liberace, Randolph Scott, et al. — all of whom, conveniently for legal purposes, are deceased." 
- In or Out: Stars on Sexuality is a compilation of celebrity quotes from stars who are homosexual, bisexual or heterosexual, and who comment on themselves, their sexuality, on others, on the closet, and on society's homophobia, as well as that of showbiz, Hollywood in particular.
- The Lavender Screen: The Gay and Lesbian Films — Their Stars, Makers, Characters, and Critics is a collection of gay and lesbian film lore covering movies with homoerotic themes and more or less openly gay films throughout the history of film.
- Gays and Lesbians in the Music World is one of the first books that document the artistic contributions of gay and lesbian musicians and performers. According to Madonna, it "cuts through the role-playing crap and shows the music world as it really ... is! It's camp with a High-C!"
