Character mistake: Thérèse mentioned that since 6:00pm, there was one call. After the second call from the man who commited suicide at a pay phone, there was two calls since 6:00pm. But Pierre said: "UN seul appel depuis 18h..." (ONE call since 6:00pm...) instead of "two calls."
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?
