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 the scene at the bus stop Donnie asks his sister what will happen if she tells mom and dad about him smoking a cigarette and she replies "you will put Ariel in the garbage disposal." It would be impossible to posses an Ariel doll because Ariel did not come out until 1989, and the movie takes place in 1988.
New this month 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.
