HR:

Fresh from the success of "Twilight," Kristen Stewart is set to portray Joan Jett in "The Runaways," the rock 'n' roll biopic of the 1970s all-girl band.Video director Floria Sigismondi wrote the screenplay and is directing, while John and Art Linson and River Road Entertainment's Bill Pohlad are producing. Jett will act as an executive producer.The Runaways were hugely influential as the first successful all-girl hard rock band; its members included guitarists Jett and Lita Ford, drummer Sandy West, singer-keyboardist Cherie Currie and bassist Jackie Fox. The band was brought together in late 1975 by impresario Kim Fowley, who thought a novelty act of teenaged girls performing in leather and lace would be an easy sell, but the girls ended up proving to be serious and influential musicians with songs like "Cherry Bomb." The band lasted about four years together, falling apart over management and money issues.
