(from Wiki)
Battle: Los Angeles is an upcoming 2011 science fiction film directed by Jonathan Liebesman, and starring Aaron Eckhart, Michelle Rodriguez, Michael Pena, Ne-Yo, and Bridget Moynahan. The film's premise is inspired by the 1942 Battle of Los Angeles incident (sometimes called the "Great Los Angeles Air Raid of 1942") in which a presumed enemy attack, later deemed a "false alarm," led to an hour-long anti-aircraft artillery bombardment over the city of Los Angeles. The film is set in modern day Los Angeles and follows a platoon of Marines and Airmen during a global alien invasion. READ MORE
