Continuity mistake: When she gets the pizza from the guy at the door, it is in a white box. When she goes in and sets it on the counter, it is in a brown pizza box. Then later, when she is running away covered in blood, she grabs the knife on top of the pizza box, and it is white again.
Continuity mistake: During the fight in the bathroom, Zoe and the villain break a bathroom stall door and side-wall down. In the next shot the door is back up in its original position. It is the same door that is beside the urinal, not another stall, as it's a small bathroom with only one stall and urinal. (00:28:30 - 00:30:00)
Continuity mistake: Catherine goes home after sex with Chloe yet she later receives a picture on her phone from Chloe in which she's asleep afterwards. When did she fall asleep?
Suggested correction: There's no indication that she went straight home. Lots of people doze off after sex.
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 the woman almost overturns the shelves when Wes is signing his book, you can see that in the first shot, all the upstanding books are falling down. In the next shot some are upright, and then in the next they are all lying down again. (00:18:00)

Continuity mistake: When Bison beats Cantana to death, blood splatters onto his face. It disappears and re-appears from shot to shot during the scene. (Unrated version only).
