Director Peter Berg's upcoming movie Battleship was fueled by his lifelong love of the Navy, and he managed to talk the military into granting him a few pretty major favors during filming. The biggest? Taking the USS Missouri—which has for years served a museum stationed at Pearl Harbor—out on the water for one especially memorable sequence. Getting special favors from the government was just one challenge Peter took on with the project. He also hired relative movie newcomer Brooklyn Decker and total acting novice Rihanna for two of the key roles. We talked to Peter about putting both women to the test and, during our chat, even got a surprise visit from leading man Taylor Kitsch. Check out our interview and catch Battleship in theaters on May 18.
