Roman Polanski directs Catherine Deneuve, Ian Hendry and Yvonne Furneaux in this psychological horror where a fragile girl loses her mind when left alone in her Swinging London flatshare.
A genuinely affecting sequence of incongruous sounds, ominous malaise and bursts of surreal terror. Deneuve hooks you in with a compelling turn as the near silent quivering waif. Polanski ramps up the claustrophobia with angles and neat effects that crush you tightly in within her mental trap. Still an artful and potent shocker 50 years on.
