The only catch is that Law's character is genuinely into the scene, while Damon's is faking it to befriend him. (Who can blame him? The train-spotter tendencies entailed in being a jazz buff would be a red rag to any fraudster.) Unfortunately, Law sees straight through Damon, which is no surprise to critic Jack Massarik. "A jazz musician would never be taken in by someone who was bluffing it," he says. If only Mr Ripley had had Mr Massarik and Graham Marsh, author of The Cover Art of Blue Note Records, around to offer a few tips, he might have got away with his poseur deception. But that, of course, would have been a different film, with an upbeat, harmonious ending.
