Factual error: When Donnie returns to his house to find a jet engine has landed on it, we see them lift the jet engine up with the crane. Yet his family, complete with 5 year old girl, are standing right in front of the crane. Plus workmen are milling around underneath and about 4 FAA officials come from inside the house. They are lifting a 2000lb jet engine, and all these people are allowed to wander around while it's 20ft above them?
Factual error: In Donnie’s front lawn of his home which is supposedly Middlesex, Virginia, there are two very noticeable Sago Palms. Sago Palms are subtropical plants that grow nowhere near Middlesex. This is a direct clue to the filming location of Southern California...and not Virginia, which receives some snowfall on an annual basis.
