On the heels of their Sundance rockumentary debut "Fast Future Generation," twin rock stars Benji and Joel Madden of Good Charlotte are getting into the moviemaking business.

They have teamed with the documentary's director, Marvin Scott Jarrett, to form the youth-oriented production company Fast Future Films. The company's first project, "Valley of the Damned," is slated to begin production in the spring.

Jarrett will direct the thriller, a story of a brother and sister who move to Phoenix and discover the body of a teenager. Joel Madden will star in the project, with additional casting to be announced soon.

Jarrett, who will continue working as editor-in-chief of Nylon, is the founder of two other magazines, Ray Gun and Bikini. Good Charlotte is working on a follow-up to its 2004 Epic album "The Chronicles of Life and Death."
