This is the last film of Claude Chabrol's 'Hélène cycle', in which actress Stéphane Audran starred, playing characters called Hélène in The Unfaithful Wife (1969), The Butcher (1970), and The Breach (1970). The only film in the cycle which Audran didn't star in was This Man Must Die (1969), the role of a character called Hélène was instead played by Caroline Cellier.
The house and garden of the couple in the film, Charles and Hélène Masson - played by Michel Bouquet and Stéphane Audran - were designed and built by the architect Jack Hamoniau.
