Announced in April of 2007, "Neon Angels", a film to produced by Art and John Linson, will finally tell the real tale of the Runaways. The biographical film will be based on a memoir by Currie that reveals details about the girls' experiences with music, sex, and drugs. Floria Sigismondi, who has also directed videos for Marilyn Manson, the White Stripes, and David Bowie, will write and direct. Jett will be an executive-producer, along with her manager and producer, Kenny Laguna and Brian Young.

Jett told Daily Variety, "We certainly utilized to our advantage our image as teenage girls who wore titillating clothes. But we also became an excellent band and made it OK for girls to play rock and roll. It got hard once people focused more on what we were wearing than what we were playing."
