Factual error: Trudie and her family are released from jail because David, being the victim of kidnapping, decided not to press charges. That's not how things work. It's not up to the victim to decide whether or not to press charges. It's up to the prosecutor to decide or not to press charges.
Visible crew/equipment: When David is chasing Trudie around island in the kitchen before she smashes the cellphone, out of the kitchen window you can see one of the set crew members walking by in the snow.
