It's David Arquette!
That's right, it's everyone's favorite bumbling deputy, Dewey Riley, aka David Arquette. Courteney Cox's ex posted this pic to Twitter November 5, 2012, and we're happy to confirm that it is, indeed, for a movie role.
You can catch the scantily clad Arquette in the post-apocalyptic sci-fi flick Orion due out in 2013.
