Best drama movie mistakes of 1966
Other mistake: The movie concludes with George Peppard crashing a test monoplane. The shot is from James Mason's office, looking out over the airfield. We hear the sound of the diving plane, but do not see it. After the camera has been focused on the field for a few seconds, we see a large explosion, which is meant to represent the crashing plane. The falling plane is missing. From the position of the shot, we should have seen the crashing plane.
Continuity mistake: The cars change shape frequently during the movie. That depends on the fact that many scenes were filmed at real races, with real F-1 cars. The cars that the actors drove were, for the most part, disguised F-3 racers. There are at least three fake Ferraris, and they all look different. One of them seems to have been built to resemble a 1965 F-1, but altered to look like a 1966 model. The non-existent Yamura (built to resemble a Maclaren), that James Garner drives is actually two cars with different chassis, one of them seems to be used very little, except when it catches fire in a scene.
