Hard to choose fom that list. I picked Star Trek 2, simply because I loved Abrams' take on the last one.
My choice would have easily been The Hobbit until recently when they announced that they were making it into 3 movies as opposed to 2. This just screams cash grab to me. I can't see how they can stretch that out into 3 movies, even with adding in all the appendices.
I am also extremely excited for Skyfall and Iron Man, and strangely enough, for Man of Steel. I think Zack Snyder will do Supes up right this time.
Really? Aren't the 2 movies already filmed, though? Maybe we'll get lucky and the 3rd one will be The Silmarillion.
