Here’s one I did earlier: Interlude (1968):

Oskar Werner's Stefan is terrific, marvellously convincing as a dynamic, thrusting, celebrity conductor (the man has rhythm!): a sort of cool, younger version of a Von Karajan or a blonde Daniel Barenboim, a Maestro for the Swinging Sixties, with a so-called 'Chinese Eye' drop-head Continental Bentley in chocolate brown, an elegant Society wife Antonia (Virginia Maskell), and a stuccoed wedding cake of a Regency country house, plus an ego as big as Beethoven's brow ("I'm surrounded by idiots!"). From memory, he doesn't wear a black polo neck, but he might well have done.
