Kristen Stewart & Dakota Fanning on Getting Racy in 'The Runaways'

Kristen Stewart and Dakota Fanning play real-life rockers Joan Jett and Cherie Currie in 'The Runaways,' and the teen stars dished to ET about tackling some of the film's racier scenes while premiering their high-voltage flick in New York on Wednesday night.

At only the age of 16, Dakota is put in questionable situations for someone of her youth while portraying Cherie. "I think there's been numerous, numerous films with kids who aren't 18 that play older [characters]," Kristen asserted. "And, in this case, she's playing her age and there's nothing exploitative about the movie. It's all very natural."

Dakota herself felt comfortable in all that she was asked to do when the director called, "Action!," and understands it is part of her line of work. She said with maturity, "I've grown up in this business thinking it's just acting; it's just pretend and that's kind of what it is for me. It's just a story and you get to transform yourself and be all different kinds of people."

We also caught up with their co-stars Riley Keough (Elvis Presley's granddaughter) and Michael Shannon, director Floria Sigismondi, and a surprise guest - Kirstie Alley! Plus, how did Joan and Cherie rate Kristen and Dakota's performances? Watch the video to find out.
