A New York cop comes to Britain and soon gets in the British law's hair: a familiar movie theme from time immemorial. Seeing that it's Harvey Keitel as the cop, we get a performance of typical clamped-down intensity - a man doing his job despite the weight of the world (and a broken marriage) on his shoulders. No bad lieutenant this, though: he's even willing to go out on a limb for the young informer (Craig Kelly) who's resolved to trap the criminals he grew up with, after they become involved with the death of his father. Thandie Newton is appealing as Kelly's girl, while Terence Rigby, Keith Allen and others give traditional British portrayals of nightclub crooks. Iain Glen and John Wood are the men in macs who soon come to respect Keitel's ability to crack crimes it normally takes British bobbies months to bring to book. Traditionalists will know what we mean when we say that this is B dressed up as A.
