Factual error: The bird hovering near Manech's lighthouse is supposed to be an Albatross, but it's a Gannet.

Other: The opening scene shows a soldier lighting his cigarette from a lantern. Not only does the cigarette not touch the flame, no smoke is seen as the soldier puffs on it.

Continuity: After having sex with Mathilde, Manech places his hand on her breast. He mentions several times how he could feel her heart beat. However, when we see the scene, his hand is on her right breast.
