Moody and Pegg (1974)

Roland Moody is a newly divorced 42-year-old junk/antique dealer greatly anticipating freedom from matrimonial ties. Daphne Pegg, plain spinster and dedicated civil servant in her early thirties, leaves her home in Bolton after realising that her office boss will never agree to marry her. She heads for London and a clean break, but, owing to a rogue estate agent's dealings, finds that a man - Moody - also has a valid lease arrangement for the property she acquires. Unable to work out who is the squatter, they agree to be feuding partners and share, forging a very uncomfortable situation that is exacerbated by Moody's prodigious line of visiting girlfriends. With hilarious consequences.
