Audio problem: When Rob is yelling at the officer about the dining room set and saying "I want my dining room table and chairs!" you can hear a random bell tinkling away behind the camera. (00:17:50)
Revealing mistake: Rob and Laura are both freaking out and panicking in their bedroom when all of a sudden Jerry shows up outside their closed window. Yet Jerry puts his arms in their room, showing it's not an actual window.
Deliberate mistake: Rob is about to leave his room, and he opens the bedroom door to the noise of a loud music box that was originally being made by Laura's music box that holds jewellery in it.
Factual error: While Rob is roaming the house with a gun in his hand he chops the metal tube that the wood burning stove in the living-room is connected to. However since in real life the metal tube would be thick and insulated the tube he dented with his hand at that speed wouldn't have been damaged at all. Also, it could have broken his hand or at least sprained his hand where he wouldn't be able to use it or feel like using it.
