Remember that mushy-sounding, Irreconcilable Differences-esque movie starring the Fanning sisters that's in the works? About a little girl who sues her parents for divorce after finding out she only exists to serve as a genetic match for her dying sis? It's called My Sister's Keeper, and it just got a whole lot better-sounding. According to Variety, Alec Baldwin has joined the cast, which also includes Cameron Diaz as the mother of Dakota and Elle Fanning. Baldwin fortunately won't be playing the girls' daddy; instead he's set for the role of an attorney representing the younger, wrongfully-conceived sister. He will be going up against Diaz, whose mom character is also a former trial lawyer and will be defending herself. It's still unclear if the father role will be significant, or if the parents are now divorced, separated or simply not cinematic equals. Of course, the production has until its February start date to let us know the actor for that part.

Baldwin, who previously worked with Dakota Fanning on The Cat in the Hat, was able to sign on to My Sister's Keeper thanks in part to the writer's strike, which has halted the shooting of Baldwin's hit TV series 30 Rock (though Variety points out he is contractually allowed to schedule a movie, who's to say it would have happened with this, at this time?). I've just recently become addicted to the show specifically because of him, and hope his attorney character is close in tone to his NBC executive character, Jack Donaghy. Yet something -- perhaps the subject matter of the film -- tells me that won't be the case. Nick Cassavetes (The Notebook) will be directing from a script by Jeremy Leven (The Notebook), which was adapted from the novel by Jodi Picoult, while Mark Johnson (The Notebook) produces.
