Ron Jeremy
As the adult film industry's most prolific male performer, Ron "Hedgehog" Jeremy was a certified American pop culture icon. With over 2,000 adult film performances, including "Debbie Does Dallas Part II" (1981) and the video game spoof "Super Hornio Brothers" (1993), Jeremy was cited by the Guinness Book of World Records for the most appearances in adult movies. Even though he made his way as the preeminent male adult film actor, he constantly sought mainstream legitimacy and began appearing in Hollywood films like John Frankenheimer's "52 Pick-Up" (1986), "Dead Bang" (1989) with Don Johnson, "The Chase" (1994) with Charlie Sheen, "Reindeer Games" (2000) and "The Rules of Attraction" (2002). Though most of the roles in these films were bit parts and walk-ons, Jeremy continued to remain in the spotlight and over time turned himself into something of a cottage industry that included appearances on the second season of "The Surreal Life" (The WB/VH1, 2003-06) and in numerous music videos and video games, as well as releasing his memoirs, Ron Jeremy: The Hardest (Working) Man in Showbiz (2007). Despite his adult film past, or perhaps because of it, Jeremy managed to achieve the mainstream fame he always craved.
