Released in two separate parts : 'Smoking' (admissions in France: 411,449) and 'No Smoking' (admissions in France: 355,942).
There are actually 8 versions of the play "Intimate Exchanges", but the director cut two of the possible outcomes in order to streamline the process. Also, the material in them was thought to be 'too British' for easy translation.
The two stars of these films also starred in the film version of Alan Ayckbourn's Private Fears in Public Places (2006), also directed by Alain Resnais. Resnais and Sabine Azéma are husband and wife.
