Character mistake: This happens when a man committed suicide while calling the SOS with a pay phone. When he shot himself, Thérèse said: "Rappelez-moi d'une cabine qui fonctionne." (Call me back on another pay phone that works.) How can Thérèse knows that the man is calling from a pay phone?
Visible crew/equipment: Mr. Preskovitch came to visit Pierre and Thérèse to give "doubitchou" (chocolates). When Mr. Preskovitch said "Vous ne les goûtez pas, Mme. Thérèse?" [You don't want to eat one, Mrs. Thérèse?], a boom mic can be seen in the reflection of the right door, in the top right pane of glass. (00:26:25)
