In the mid 1970s, Leslie relocated to the Mill Valley area in California and began performing in adult films. His first film was Coming Attractions (1976). He was a performer in almost 300 adult films and won numerous awards during his days as a performer. He appeared with some of the era’s most noted porn stars, including Traci Lords and John Holmes, as well as Seka, Kay Parker, and Annette Haven. His most noteworthy roles were in Obsessed (1977), Desires Within Young Girls (1977), A Coming of Angels (1977), Dracula Sucks (aka Lust At First Bite) (1978), Pretty Peaches (1979), Insatiable (1980), Nothing To Hide (1981), and Talk Dirty To Me, Part II (1982).

He was one of the first porn actors to make the transition from performing to directing, beginning with 1987’s Nightshift Nurses. Since then, he directed more than 90 adult movies, including The Chameleon (1989), Curse of the Catwoman (1992), Dog Walker (1994), and Drop Sex (1997), along with the Voyeur’ ‘, Fresh Meat, and Crack Her Jack series. He won many awards for his work behind the cameras as well. Though much of his later work, in keeping with current trends in adult video, was in the gonzo genre, such as the “Fresh Meat” and “Crack Her Jack” series, Leslie continued to make feature films, or “sex dramas”; most recently, in 2007 he directed the film Brianna Love, Her Fine, Sexy Self.

He was a member of the AVN and XRCO Halls of Fame.

John Leslie died of a heart attack at the age of 65 on December 5, 2010, at his home in Mill Valley, California.
