A Severed Head

Upon learning that his wife Antonia (Lee Remick) is having an affair with his best friend, Palmer (Richard Attenborough), who is also her psychiatrist, Martin Lynch-Gibbon (Ian Holm) is plunged into agony. Martin's longstanding mistress Georgie (Jennie Linden) is ecstatic with the hope that Martin, now free from Antonia, will marry her - but Martin is too busy trying to woo his wife back to pay much attention to Georgie, leaving her free to explore other partners. Throw in a few more characters/love partners: Martin's brother, and Palmer's sister (Clive Revill and Claire Bloom), and the finale of this boudoir version of musical chairs becomes impossible to guess!
