Scotman Paul McGuigan (Gangster No. 1) contributes this crazed crime story about a case of mistaken identity that leaves a down-on-his luck slob (Josh Hartnett) stuck in the middle of a gang war between Ben Kingsley and Morgan Freeman (scary). To make matters worse, he's being pursued by an infamous assassin (Bruce Willis). Our boy Slevin's situation is slightly ameliorated by the attentions of Lucy Liu, but the body count continues to rise. At times the film becomes wrapped up in its own twisty cleverness--which is wedged some where between the filmy smartness of Hitchcock and the showy self-awareness of Tarantino. Still, it's a hell of zippy ride. 110 minutes R.
