Little Dakota Fanning is all grown up and making everyone feel like a pedophile. Alongside Kristen Stewart, Dakota shakes her distressingly young chest in this music video for Joan Jett biopic The Runaways. Somewhere, Taylor Momsen is seething with envy.

But mostly sex. This isn't The Runaways trailer that hints at Fanning's metamorphosis from innocent pupa to sexed-up butterfly, this is the music video for "Cherry Bomb", which shoves Fanning's drug-addled, hypersexual portrayal of Cherie Currie down your throat.

If 'Avatar' makes as much money as 20th Century Fox basically needs it to, we may never see a plain 2D movie again. Variety reports that 3D films tripled their B.O. take this year, to $1.3 billion.
