Factual error: When Paul flies off the hood of the crash test car when it stops, he should have kept going in a straight line. Instead, he flies off to the side at a sharp angle and lands in the seat testing department.
Continuity mistake: Three types of airplanes are used for the flight to Chicago. The exterior loading and taxi shots show a Boeing 747. The interior shots show another Boeing (the overhead bins, sidewall panels, etc., are distinctively Boeing), but it's smaller like a 767, because it only has 2 seats by the window and 3 in the center. The exterior shot in flight shows a Lockheed L1011, with its distinctive S-duct for the center engine.
Deliberate mistake: Why would Richard, big Tom's 'right hand man,' have to drive his cherished vintage car on a business trip that would take him hundreds, if not a thousand miles? He surely could have taken a company vehicle. Of course, then they couldn't do the 'car slowly and humorously being destroyed' shtick.Brian Katcher
