The ever-so-muscular Chris Hemsworth (aka Thor) goes from wielding a hammer to a keyboard in the trailer for Michael Mann's (Heat, Collateral) upcoming movie, Blackhat. The thriller follows Nicholas Hathaway (Hemsworth), a convict serving time for hacking, as he is released back into the world to help the government hunt down a cybercrime network. I have to be honest about this trailer: I love a sexy bad boy/genius kicking butt set to a slow cover of Eric Clapton's "Knocking on Heaven's Door." The movie looks sleek, and it's set for a Jan. 16 release date. Watch the trailer to also get a peek at costar Viola Davis.
