Roy Boulting’s 1970 sex comedy, adapted from a then long-running stage play, carries an over-inflated reputation. The set-pieces now seem clunky, as Peter Sellers, looking distinctly uncomfortable, plays a smarmy, lascivious TV star who meets his nemesis in plucky Goldie Hawn. Watching their free love will cost you. Still, the marvellous Diana Dors lifts it briefly.
