Check out this new still of Kristen Stewart as the legendary Joan Jett in the upcoming The Runaways biopic.

The 19-year-old actress caught up with SPIN mag on the set and shared about taking on the role, “I was terrified. I was going, ‘Oh my God, why the **** am I here?’ Not like I shouldn’t be, but just, ‘How is this happening?’ This was the coolest job I’d had — it was something different during a long stint of something very much the same. I knew I needed to cut off [Twilight character] Bella’s long hair. I needed to be able to throw my head around and feel the sweat dripping.”

Kristen continued about things around the set, “The things that were wrong drove me crazy, and I annoyed the shit out of Floria [Sigismondi, director]. She was always telling me, ‘Kristen, we’re not doing that movie.’ Even Joan was like, ‘Yeah, it’s fine, dude. Relax.’”

The Runaways opens NEXT Friday, March 19th.
