"The Dark Knight" star Aaron Eckhart has been tapped to battle aliens in L.A. in a new sci-fi action flick, "Battle: Los Angeles."

The 40-year-old actor, who played villain Harvey Dent/Two-Face in the smash 2008 Batman film, will be playing the leader of a platoon in combat against invading aliens.

Jonathan Liebesman will be directing for Columbia, while Neal Moritz and his Original Film company are producing, as per the Hollywood Reporter.

The new project puts Eckhart on the lead role on an action movie for the first time. He had been involved in less mainstream films, including 1997's "In The Company of Men," in which he won the Independent Spirit Award for Best Debut Performance and the Satellite Award for Outstanding New Talent.

He will next be seen in a romantic drama film alongside Jennifer Aniston in "Traveling."
