Asghar Farhadi wrote the script in Persian and then lived in France for two years in order to better understand the rhythms of the French language so that he would be able to more accurately judge the translation of his script and the performance of his actors.
Pauline Burlet was chosen by director Asghar Farhadi for the role of Lucie because of her similarity with Marion Cotillard, who was going to play her mother in the film. However, Cotillard dropped out because Farhadi always insists on a rehearsal period with his actors before filming, something she could not commit to due to prior engagements.
