A movie with well known actors, so you ask yourself "Why did they agree to that?"
Before I would said Mad Dog and Glory with Uma Thurman, Robert Dinero and Bill Murry. Seeing Uma Thurman was nice, but it didn't move the story forward at all. Wasn't necessary to the movie at all.
Now having just watched it I'd vote for Monster's Ball with Billy Bob Thornton, Halle Berry and Heath Ledger. Again, nice to see Halle Berry, but they could have shot around it and it wouldn't have made any difference.
Any other nominations?
