The theatrical trailer for Jonathan Liebesman's Battle: Los Angeles is now available online.  Starring Aaron Eckhart, Michelle Rodriguez, Bridget Moynahan, and Michael Pena, the film is of the "alien invasion" variety and follows a Marine staff sergeant (Eckhart) as he and his team take on the unwelcome guests.  A few months ago, the film premiered a great teaser trailer.  While the theatrical trailer doesn't quite live up to that stellar cut, it's still an effective and suspenseful 2:30 minutes that manages to raise my modestly high expectations for the film even higher.To check out the trailer for yourself, hit the jump.  Battle: Los Angeles hits theaters March 11, 2011.Here's the trailer [via Yahoo!

Here's a synopsis for Battle: Los Angeles:

For years, there have been documented cases of UFO sightings around the world -- Buenos Aires, Seoul, France, Germany, China. But in 2011, what were once just sightings will become a terrifying reality when Earth is attacked by unknown forces. As people everywhere watch the world's great cities fall, Los Angeles becomes the last stand for mankind in a battle no one expected. It's up to a Marine staff sergeant and his new platoon to draw a line in the sand as they take on an enemy unlike any they've ever encountered before.
