Universal has released the third trailer for the film Battleship. Yep, that's right they made a film based upon that boring old board game you played as a child. I've got a feeling that this film is going to be a bigger box office bomb then John Carter was. Anyway it opens in the United States and Canada on May 18th and stars Liam Neeson, Brooklyn Decker and Rihanna. Hopefully they managed to have a real script for this one as opposed to the storyline being entirely special-effects thrill-based.
