The Thomas Crown Affair (1968)

This is a wonderfully understated, classy heist movie that demonstrates clearly the panache of Steve McQueen as an actor. In the title role, he is a millionaire who presents an outward image of a man who has everything, but privately is meticulously planning and executing a bank robbery that nets him over $2 million. When the insurers bring in their best investigator - the glamorous and sassy Faye Dunaway, she quickly susses out what's what and we have a cunning game of cat and mouse tinged with some unsentimental romance. The Michel Legrand score is superb; the dialogue taut, occasionally witty and Norman Jewison's direction is subtle and attractive leading to the scene at the end that you could never forget. Great stuff.
