Jet Li in UnleashedUNLEASHED

After its opening credits, Unleashed gets right down to business. Even if you haven't seen the trailers, the first five minutes of director Louis Leterrier's thriller will have you up to speed: Set in Glasgow, the film stars Jet Li as Danny, a young man raised by the malevolent crime boss Bart (Bob Hoskins) to be a human pit bull. If any of Bart's associates owe him money and refuse to pay, Bart introduces them to Danny, removes the Tiffany dog collar, and the welshers find themselves in a world of hurt.

Brad Pitt and Julia Roberts in The MexicanTHE MEXICAN

We've had the evidence for years, but I think it's time we made it official: Brad Pitt is a gonzo supporting player stuck in a (rather dull) leading man's body. Recently, he portrayed the heavily-accented Irish boxer in Snatch, giving the film a jolt of pure, comedic adrenalin - his screen time was brief, but he was the most entertaining performer in the movie - and when he appeared as a supporting actor in 12 Monkeys, Thelma & Louise, and True Romance (probably his best, and easily his funniest, screen work), his performances were well-calibrated and often inspired. Pitt can display a true flair for off-kilter comedy; it's telling that his most enjoyable lead performance has come from the darkly comic cult film Fight Club, where his Tyler Durden was clearly one of Pitt's nutjob character roles gone berserk.
