Chicago Reader review:
Jerzy Skolimowski's first English-language film (1970), made just after his departure from Poland—which may help account for the film's unusually strong sense of displacement, unfamiliarity, and isolation. These are feelings shared by the film's protagonist, a British teenager (John Moulder-Brown) whose job as an attendant at a public bath brings him his first experiences with sexuality and mortality. It's one of the most authentic films about adolescence that I know, yet through mise-en-scene Skolimowski effortlessly expands detailed, specific situations into haunting universal images, much as he did in his later masterpiece Moonlighting. With Jane Asher and Diana Dors.
Here (and above) is the trailer.
