There aren't many stains on Tom Cruise's on-screen persona but that could change with Collateral, as Robin Walker explains.
He's an undisputed Hollywood superstar, an apparent Mr Nice Guy and an all-round onscreen hero. But the A-lister seems keen to show us a darker side ( on screen, at any rate.
Following his recent role as a haunted American civil war veteran in 2003's Last Samurai, he now plays a cold-blooded hitman in Collateral, delivering a performance that is shaking up his perfect smile and sex appeal.
