Revealing mistake: "The Crash": Due to the use of both models and stock footage, what is supposed to be one airplane has three very different appearances. As the passengers board, we see the "real" plane. In the air, it's another plane altogether (stock footage). When it crashes (a model), it looks completely different yet again.
Revealing mistake: "Darien Comes Home": When Zack puts the body in the driver's seat, the car is a black 1990s sedan. When he pushes it over the cliff, however, stock footage turns the car into a much older model that's now gray instead of black. (00:04:50)
