Dakota Fanning has dropped out of the film project My Sister’s Keeper, a movie which would have united Dakota and her little sister, Elle, in film for the first time. The elder Fanning passed on the film because the role called for her to shave her hair, so Elle quickly backed out as well.

Never fear - there are plenty of child actresses around. Er, maybe just one - Abigail Breslin. The Definitely, Maybe star (who is suddenly all over the place) will now take over for Elle Fanning while Sofia Vassilieva (from Medium) will fill in for Dakota.

Production will begin in March, barring any future major casting changes.
