Another installment to the recent
onslaught of alien invasion films, Battle: Los Angeles is based on famous historical UFO sightings and events such as the 1942 LA incident where an unidentified aircraft entered military airspace and was subject to artillery fire.
Battle: Los Angeles follows one Marine platoon's attempt to defend the city
of Los Angeles (or more accurately, Santa Monica) from the
onslaught of a powerful and incredibly tough space
alien invasion of the major cities
of Earth.
