Roman Polanski's first English-language film.
Features the first depiction of female orgasm (sound only) to be passed by the British Board of Film Censors.
In his autobiography, Roman Polanski admitted that he and co-writer Gérard Brach came up with the film so as to have a commercial success which would then help them fund the making of Cul-de-sac, a much more personal project for them.
Premiere voted this movie as one of "The 25 Most Dangerous Movies".
The scene where Catherine Deneuve stumbles across the bridge and down the street was filmed at Hammersmith Bridge, London.
This film, along with Rosemary's Baby and The Tenant, forms a loose trilogy by Roman Polanski about the horrors of apartment/city dwelling.
