Chicago Reader review:
'Written with Jerzy Skolimowski (Moonlighting), this 1962 production was Roman Polanski's first feature film, and there are those who would still call it his best. A middle-aged married couple, intrigued by a young blond hitchhiker, invite him to spend a weekend on their yacht. The sexual tensions build slowly and subtly, and when they explode into violence, it seems to be the desired result.' JR Jones
