Tom Cruise in CollateralCOLLATERAL

Collateral's plot is so High Concept you can barely believe it hasn't been filmed before: A cab driver (Jamie Foxx) unknowingly picks up a hired assassin (Tom Cruise) as a fare, and spends a long, strange evening chauffeuring him from one execution site to another, all the while trying to prevent the killer from performing his rounds without, of course, getting himself killed in the process.

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.
