Shep Gordon has had one of the most fascinating careers in Hollywood. He's a talent manager whose client roster includes Alice Cooper, Anne Murray, Blondie, Teddy Pendergrass and Groucho Marx.

He got his start managing musicians when he met Janice Joplin and Jimi Hendrix in a chance encounter at an L.A. motel and sold them marijuana. Those and other exploits are chronicled in a new documentary directed by Mike Myers called "Supermensch."

The film opens at the Landmark theater in Los Angeles Friday, June 6.
