Continuity mistake: When the Man and Woman have lost Alice, they look in the kitchen to find her, and the Woman starts opening up some cabinets and in the process she leaves some of the doors open. Then in the next shot, the cabinet doors that are open have now changed, and some doors that were open in the previous shot are now closed.
Factual error: When the cop (Bobby) asks the woman if it's her van, she says she found it when she got home. In actuality, the police would get suspicious because she didn't report it. Someone comes home and sees someone else's vehicle parked in their driveway and neither her or the man call to report it (at the very least to have it towed)?
