TRAILER: The Hunt Is On for Osama bin Laden in 'Zero Dark Thirty'

Director Kathryn Bigelow's Zero Dark Thirty has been shrouded in secrecy. We got a trailer that revealed just a bit over the summer, but beyond that, we don't know much about the film that chronicles the hunt for and killing of Osama bin Laden. That changed today with the release of the second full trailer for Zero Dark Thirty in addition to the news that James Gandolfini would be playing then-CIA Director Leon Panetta.

Looks like we're going to have to get used to Parks and Recreation's Chris Pratt playing serious roles, as it appears that he plays one a SEAL in Zero Dark Thirty. The film also stars Jessica Chastain, Joel Edgerton, Mark Strong and Kyle Chandler. Zero Dark Thirty will debut in theaters on Dec. 19, 2012. Check out the new trailer after the jump.
