In 2006 Sasha Grey, got her start in porn and, according to her website, "used the industry as a platform for experimentation and performance art, and as a means to encourage individuals to take pride in their sexuality."

Sylvester Stallone was kind of cocky before he was Rocky, with a role in The Party at Kitty’s and Studs. As ridiculous a name as that is, it's what got him a role as an extra Robert Redford's Downhill Racer. We guess you could say it was all downhill from there!
