Please do not read ahead if either you don't care about one of the greatest movie trilogies ever (probably between Star Wars and Back to the Future in the pecking order) or you are such a big fan, you do not want anything to be revealed before you have popcorn in hand on July 20th.
This was revealed when the publicity for Wrath of the Titans, in which Neeson plays Zeus, came out. It reads "Neeson next appears in Peter Berg's actioner Battleship and he also will be seen in Christopher Nolan's much-anticipated action thriller The Dark Knight Rises."
So, there you have it. One of Batman's greatest enemies will be back to fight the Dark Knight in the finale of this trilogy. Awesome. At least we will have one villain that can be understood. Yes, I'm talking to you Bane.
Dark Knight Rises most recent trailer is below. The movie is out July 20th. Oh, one more trilogy that's fantastic people forget about... Toy Story.
