Donald Pleasence and Francoise Dorleac play a mismatched couple - he effeminate and petulant, she sensual and enigmatic - who share a bizzare sexual relationship, living in a remote castle. Their very isolation from the world prevents their eccentric partnership from foundering. Only an outsider can disrupt their make-believe lifestyle. That disruption arrives in the belligerent form of Richard and Albert, two oddball gangsters straight out of a 1940's film noir, wounded, desperate and on the run. They demand shelter, and as Richard waits for instructions from his gangland boss, he slips into a dangerous round of gameplaying with his unwilling hosts. But it seems that Richard is not always to have the upper hand. With its larger-than-life performances, wicked black humour and superb use of striking outdoor locations - the film was shot on Holy Island in Northumberland - Polanski has created an exceptional film which is very different to but no less memorable than Repulsion.
