Jack Black / also part of "Tenaciuos D"
Jack Black is the wild-eyed, manic star of the hit comedy School of Rock (2003, directed by Richard Linklater) and half of the comedy-rock duo Tenacious D. He started in the movies in the early 1990s with small but memorable parts in movies, including Tim Burton's Mars Attacks! (1996) and Enemy of the State (1998, with Will Smith). By 2000 Tenacious D had earned a national audience by way of a short-lived show, and Black's film career was taking off. In a supporting role, he stole the show in High Fidelity (2000, starring John Cusack) and started getting lead roles in comedies, including Shallow Hal (2001, with Gwyneth Paltrow) and Orange County (2002). In 2004 he was the voice of Lenny in the animated feature Shark Tale (2004) and won the lead role of Carl Denham in Peter Jackson's King Kong (2005, with Adrien Brody).
Extra credit: Black was also the star of Heat Vision and Jack (1999, with the voice of Owen Wilson), a tongue-in-cheek TV series directed by Ben Stiller that was made for Fox television but never broadcast.
