Back in the day, John Holmes was the biggest -- and therefore the best -- in the biz. "Johnny Wadd" starred in more than 2000 adult productions and reportedly bedded more than 10,000 women over the course of his career -- including his wife.
Probably the only guy who might really have been hornier than Ron Jeremy, he was well-endowed. Really, really well-endowed. He died of AIDS in '88, after being tried and acquitted for the infamous "Laurel Canyon" murders in '81, on which the biopic Wonderland is based.
Hard Candy, being shown in 3-D at the Roxy, was Holmes' last film before his career went flaccid. (Wonderland is currently at The Roxy, too.) And if you're too chicken to see him in action, be him in action at http://www.whoisjohnholmes.com/wad.html.
