'Battle: LA' tops box office

Shoving aside its many critics, Battle: Los Angeles, has manoeuvred straight to number one at the US box office. This should come as little surprise considering that the film's sophisticated viral marketing campaign - central to which was an authentic photograph of the real life 'Battle of Los Angeles' of 1942 - began as far back as July of last year.

While Battle: Los Angeles brought in an impressive $36 million in its opening weekend, the other UFO/alien movie of the moment - Disney's Mars Needs Moms - opened to a disappointing $6.8 million.
