MTV has the exclusive new teaser for The Runaways, the film about the titular all-girl 70’s rock band. The film will follow their rise to superstardom amidst a turbulent relationship with abusive manager Kim Fowley (Michael Shannon), with lead singer Cherie Currie (Dakota Fanning) and lead guitarist Joan Jett (Kristen Stewart) serving as the focal points.

The little we do see looks promising enough, and though Fanning appears to lack the timbre of Currie’s voice, she’s certainly got the sass and attitude. This will be an interesting film for both Fanning and Stewart; their most overtly complex roles to date where their maturation as performers will be placed front and center. I’m intrigued to see how they do, and whether or not this will be the movie that pushes them from being child/teenaged actresses into just actresses. Long-time music video director Floria Sigismondi will make her feature debut from her own script, and so far it looks like she’s captured the mix of posh and grime that would become a distinct part of The Runaways’ style.

Check out the teaser after the jump.

The Runaways will debut at Sundance in January before hitting theaters on March 19, 2010.
