The only problem with casting Kristen Stewart as Joan Jett and Dakota Fanning as Cherie Currie is that Joan Jett is still an intense badass and you can watch Cherie Currie be the most frighteningly damaged burnout teenager in Foxes on the internet. But we will reserve judgment on this one since Runaways director Floria Sigismondi is pretty awesome and no one has yet confirmed that Scott Baio does not make a cameo.
