Continuity mistake: Ilya is standing across from and about midway between Chris and Alicia. He spears the shovel into the ground, but it unintentionally falls over to his right (mostly off-screen). The next view of the shovel shows it has fallen to Ilya's left. (The entire shovel is to the right of Chris, which would be too far regardless of which direction the shovel's handle fell.) In the next view, the shovel's blade is opposite Chris' left foot and later the angle is different. (00:36:30)
Continuity mistake: Théo shows up in class unannounced. The teacher tells him to sit next to "that girl", mistaking Daniel for one. The classmates of course have a cackle at that; the girl at the desk behind Daniel's laughs holding a pen in her left hand at first, right hand at the cut. (00:08:50)

Continuity mistake: Spoiler alert: About halfway through the movie, we see Emma Roberts coming out of the shower, and the camera focuses on the gunshot wound on her shoulder, with the round scar of the entry wound on her back, and the much rougher, ragged scar of the exit wound on her front. Then at the end of the movie, where it's revealed that Kiernan Shipka and Emma Roberts were actually playing the same character, just nine years apart, Kiernan Shipka gets shot by the police officer when he finds her in the room with the severed heads. Problem is: she was facing the officer. The scars on Emma Roberts are the wrong way around. (00:31:05 - 01:15:35)

Continuity mistake: When Henry meets Maggie, in official capacity this time, the conversation has continuity errors in the hand position of Brooke Burns. She points the finger at him, lowers the hand as he says "I know you!", but the hand is back up and pointing in the next shot. Likewise, when she asks him if he's a witness, her hand goes from closed to open to closed again. (00:19:20)
Continuity mistake: Ray is on the phone with his girlfriend; as he says "Whatever you say, Ashley", the green scrapbook is closed. It is open again next, just as it was open before. (00:02:00)
