When the hijacker jumps out of the black Chevrolet El Camino and it goes over the hill, it turns into a blue Ford Ranchero as it crashes and explodes.
In several scenes, trucks are shown driving through falling snow -- only to arrive at destinations within short driving distance where snow is not only not falling, but not even on the ground.
At almost 17 minutes into the movie when you see Rain 7 Duke coming up to help look for the missing driver you see 3 people in the truck cab. Jerry Reed is not driving the truck somebody else is driving.
The movie is supposed to take place in the States. However, take notice to nearly every vehicle in the film - they all have Ontario plates!
The film is set in the U.S., but in the climactic scenes Toronto's C.N. Tower appears in the middle distance; much too close for any U.S. location, even in New York state.
