The Dark Knight
I was interested in seeing "Tropic Thunder" in the theaters, and I think that I'd appreciate going to see "Frost/Nixon", but I think this is a year that I end up skipping most of the nominees.
And, to be clear, I'm looking at the full "official ballot", which has nominees for best sound mixing, best visual effects, and best adapted screenplay. Of the best picture nominees, I've seen a total of zero. "Frost/Nixon" would bring that total up to one.
