John Curtis Holmes, professionally known as John C. Holmes or Johnny Wadd, was a renowned male pornographic actor of immense notoriety, renowned for his remarkable prolificacy, having appeared in approximately 2,500 adult loops, stag films, and pornographic feature movies during the 1970s and 1980s.
Renowned for his extraordinary genitalia, Holmes' exceptionally large penis was heavily touted as being the longest, thickest, and hardest in the porn industry, although no definitive measurement of his actual penis length exists.
Towards the conclusion of his life, Holmes gained notoriety for his involvement in the 1981 Wonderland murders, and eventually for his death resulting from complications caused by AIDS.
John Holmes has been the subject of several books, a comprehensive essay in Rolling Stone magazine, two feature-length documentaries, and has inspired two Hollywood movies, Boogie Nights and Wonderland.
