Here are a couple of quick release date changes for you.  First up, Peter Berg's Battleship is steering away from May 25, 2012 and will now hit theaters on May 18, 2012.  If it had stayed on May 25^th, it would have been fighting with Men in Black III for the same audience.  Now, Berg's blockbuster action movie will be facing off against the family flick Madagascar 3.  Of course, with these films almost two years away, release dates could shift easily.

For a release date change that's actually happening this year, the schlock horror film Piranha 3D has moved up from August 27^th to August 20^th.  Now it will go up against the comedy Lottery Ticket, the family film Nanny McPhee Returns, and the crime drama Takers.  I'd agree that it has a much better shot at winning the box office the weekend of the 20th than it does against the Eli Roth-produced horror film The Last Exorcism and Neil Marshall's bloody sword-and-sandals flick Centurion.
