I have yet to see any of the nominated movies (too cheap to pay for a movie at the theatre ), but from what I've seen as prevews, and heard through friends, Frost/Nixon was excellent. I'd be more prone to go for MILK, 'cause I think Sean Penn is a superb actor, but I can't resist Brad Pitt either. So I dunno. It's a hard choice. All these actors are wonderful in their own right.
