Factual error: When the member of Terrance Steadman's security team shoots Veronica Donovan, the wound shown in the front of her head is an exit wound, while the exit wound should have been in the back of her head since she was shot from the front. (00:36:30)
Factual error: When Veronica has a conversation with Stedman, he tells her that he can't escape and that the glass is 2 inches thick. However, if the glass in the door was 2 inches thick, the wood door would have to be 5-6 inches thick to even support such thick glass. The door would be extremely heavy. And it obviously went unnoticed by Veronica as she entered the home with no effort.
