Alec Baldwin will star alongside Dakota Fanning and Elle Fanning in the movie adaption of Jodi Picoult's My Sister's Keeper.

The 30 Rock star will play the attorney who represents a child (Elle Fanning) after she sues her parents for emancipation. The grounds? They bred her to be a genetic match who could prolong the life of her cancer-ridden sister (Dakota Fanning).

The girl's mother (Cameron Diaz) is a former trial lawyer and represents herself in court.
