The line-up for music video director Floria Sigismondi's biopic about teenage punk act The Runaways is complete - child star Alessandra Torresani has signed on to play hellraiser Lita Ford.

"Cherry Bomb" will also feature Twilight star Kristen Stewart as Joan Jett, Dakota Fanning as singer Cherie Currie and Stella Maeve as tragic drummer Sandy West, who died in 2006.

Thrilled Torresani fought for the Ford role and is thrilled to be playing the guitarist: "She’s the most incredible woman. I’m getting to meet her very soon, so that’ll be amazing. I’ll get to hear all her old stories."

She tells MTV News, "I learn the guitar starting (Monday), so that’ll be interesting. I’m very nervous about it."

Stewart is already mastering her guitar skills and bonding with Jett, who thinks she's the perfect choice to play her on the big screen.

The rocker says, "When her hair is cut and with the right make-up, Kristen should make a really good me... She has the passion for it (music), which you can't really be taught."
