Tim Sutton’s “Donnybrook” is like getting wasted on expired beer at a bar with no liquor license, fighting three strangers in a parking lot, and passing out in a pool of vomit — which may or may not be your own — at the end of the night. On a Monday. It’s a brutal, depressing, filthy motion picture. But for whatever it’s worth, that’s the point.
“Donnybrook” stars Jamie Bell as Jarhead Earl, a war veteran with two kids, a drug-addicted wife, no money, and only one chance of improving his circumstances: The Donnybrook, an illegal, bare-knuckle brawl with a $100,000 grand prize.
