Warrior‘s new trailer hit the Web today, and from the looks of it, it’s going to put the fun back into dysfunctional fighting families. Written and directed by Gavin O’Connor (Miracle), two brothers (Tom Hardy and Joel Edgerton), in remarkably different circumstances, end up training and eventually fighting each other in a mixed martial arts UFC tournament. Awkward Thanksgiving dinner, ahoy!

You’ll be forgiven if you don’t immediately recognize Inception‘s Tom Hardy — the actor certainly looks a lot different, thanks to five months of training (with a gain of 28 pounds of muscle) in order to play the younger of the brothers, a marine who returns from Iraq. And if you don’t recognize the actor playing the older brother, Joel Edgerton last seen in the terrific (and far too little seen) Animal Kingdom, you should go and rent that movie right now.

Rounding out the cast is Nick Nolte — playing the alcoholic patriarch, now sober, who trains Hardy to compete — former House star Jennifer Morrison, and Noah Emmerich. While comparisons to The Fighter will surely dog this film from now till its release on Sept. 9, it looks fascinating — and with this cast, sure to be worth seeing.
