The Runaways premiered last night at Sundance, and you can read our review of it if you're so inclined. In it, we mention that this movie doesn't feature sweet and innocent Kristen Stewart (Bella from Twilight), nor is Dakota Fanning the cute, ear-piercing little girl from War of the Worlds. They're stretching their grown-up legs to portray Joan Jett and Cherie Currie, marching straight into sex, drugs, and rock 'n roll.

As part of a roundtable interview, we talked to Kristen and Dakota yesterday in Park City about the film, how much they got to work with Joan and Cherie, and what they think people are going to say about their brief but incendiary makeout session in the movie. Kristen, who's known for being reserved in interviews at times was definitely feeling very vocal. Check out the full interview just after the break.
