If the teaser for Vince Vaughn's upcoming flick, Brawl in Cell Block 99, is any indication of the comedic actor's new role, don't expect a whole lot of laughter.

Vaughn's usual affable charm, quick wit, and, well, full head of hair are nowhere to be seen in the film. The plot focuses on Bradley Thomas (Vaughn), a boxer-turned-drug-runner who finds himself imprisoned after a deal goes horribly awry. Things continue to unravel as the violence ratchets up, and survival becomes the only goal.

From the looks of it, Vaughn is really convincing—disturbingly so. It also appears he'll be using his fists to solve problems rather than his mouth.

Watch for yourself:

Brawl in Cell Block 99 premieres September 2.
