Continuity mistake: Sophie Marceau's Jeanne meets the Hachette executive Robert (Didier Flamand). She enters the room with handbag and jacket in one hand. She then follows him into the other half of the room. Now she has her clothes in her right hand and her bag is in her left. Not just that; the man had the folder in his left hand in the first shot, but in the new one it's in his right. (00:04:25)
Continuity mistake: When Max is going to stab Naoko at the end of the movie, he grabs her by the hair, but in the next shot he's grabbing her by the chin. (01:18:30)

Continuity mistake: During the fight, the extent to which the fire (starts on top of the mound) spreads toward the ground varies. Also, the fire burns downward through snow, but does not melt the surrounding snow along the sides and bottom of the mound. (01:15:35)
Visible crew/equipment: As the camera circles Nelson exiting the SUV, you can see crew members in the RS mirror as he shuts the door. (00:26:40)
Continuity mistake: When Frida is in her room and throws the stuffed animal near the window, she sees a zombie in the pouring rain across the street. However when her boyfriend startles her in the window, he is dry and the rain and wind instantly stopped.
