MTV: So, Joan, are you a “Twilight” fan?

Joan Jett: I’d obviously heard about the movie, but before she was cast as me, I hadn’t seen it. Of course, when she was cast as me, I wanted to see the movie, and I’ve seen everything she’s done. I really enjoyed it. I thought it was really entertaining, and I’m excited that she was cast as me in “The Runaways.”
