Roger Lewis, in his Spectator review of a new biography of Charlie Chaplin by Peter Ackroyd, notes:

Chaplin died on Christmas Day 1977. Ackroyd doesn’t mention this, but the comedian’s coffin was stolen by grave robbers, who phoned Paulette Goddard, one of his wives and the co-star of The Gold Rush, hoping they could make a ransom demand. “We’ve got Chaplin,” they announced. “So what?” she said, slamming down the phone.
