Adapted from Christine Angot's eponymous novel, the film is co-written by Catherine Corsini and Laurette Polmanss.
The director feared that Niels Schneider was too young to be Philippe (10 years apart from Virginie Efira). But the Franco-Canadian actor wanted to do some tests.
Filming takes place in spring 2017, in Châteauroux, Champagne-Ardenne, Nice, Imperia and Paris.
Christine Angot was able to consult the script and comment on it with Catherine Corsini and Laurette Polmanss.
Catherine Corsini confesses that she did not have an actress in mind for the role of Rachel at the time of writing the film, let alone Virginie Efira she had never seen play.
