New Photos From "Battlefield: Los Angeles"

Liebesman, speaking to Empire, explained that his aliens come from a water-based planet and wear "inverted scuba suits, which turn air into water. I wanted them to be an army too. They have generals, they have medics, they have tactics, they have a plan. There's no hive mentality; they're individuals with self-preservation."

The film stars Aaron Eckhart as the leader of a team of Marines attempting to evacuate a group of civilians out of a war zone (formerly the City of Angels). They're up against a huge alien invasion fleet, including giant ships, little ships, seemingly endless firepower and a whole heck of a lot of scary inhabitants.
