We've worried before that the upcoming rock grrl biopic The Runaways might have trouble wooing a young female audience, and now Movieline hears that from the very first shot, the film makes its decidedly R-rated sensibility clear. Will Twilight fans be ready for an opening moment that sees a drop of blood fall on the pavement, followed by a wide shot of menstrual blood trickling down Dakota Fanning's leg (an unexpected period that prompts the first of Fanning's expletives in the film)? Perhaps only if it provokes an inappropriate, New Moon-yanked lunge from Jackson Rathbone. [PREVIOUSLY: Can The Runaways Succeed Where Whip It and Jennifer's Body Failed?]
