Forbidden to the Public (1949)

Hervé Montagne, a famous but awfully self-satisfied playwright, is furious when he learns that the actress signed to lead in his latest play will not be able to play the part on account of pregnancy. All the more as no other great actress is available. Well, in fact there IS one, Gabrielle Tristan, a great name of the French stage. The only trouble is that she is Hervé's ex-wife and that they have not been on speaking terms for ten tears.
