Dakota Fanning will "blow the minds" of her fans when she plays a rock chick.

The 15-year-old actress appears alongside Kristen Stewart in Joan Jett biopic 'The Runaways' and their co-star Scout Taylor-Compton insists their hard work in mastering musicianship has paid off.

She said: "We performed for like eight hours straight. It was crazy. Basically, I felt like I was in a band and I miss it. I miss rehearsal.

"All of us had something to do. Dakota will blow your mind. She's amazing in it and so is Kristen. We learned a lot of songs. We did a lot of performances."

Scout plays guitarist Lita Ford in the movie, and although she didn't get to meet her alter ego, she loved having the chance to rub shoulders with the real-life members of The Runaways.

She added to website Starpulse.com: "I didn't meet Lita but Joan Jett was always there during band practice, during the filming. She was always there, always hanging out with us. It was great. And Cheri Currie was there."

In the movie, Dakota plays Cheri, while Kristen portrays Joan.
