Goofs

When the car crashes on the test track, the rear bumper comes off. Moments later when the damaged car drives away, the rear bumper is fine.

When Tucker is in his plant contemplating his impending demise, he drops his cigarette and puts it out, but in the next scene, he continues to press down his foot like there's a cigarette underneath it, but when he walks away nothing is there.

A wide shot is used showing the jury entering the courtroom with their verdict. The judge is shown standing as required for proper courtroom etiquette. Partway through the jury's entrance a cut is made to a slightly tighter shot but now the judge is dishonorably shown as seated.

During the nighttime scene between Tucker and Abe outside the Tucker plant, the red lit Tucker sign is on, then off, then on again before it is finally switched off along with all the other exterior lights.

The transport plane that the car is loaded into on the ground is a C-123 Provider, which made its first flight in October, 1949.

At the 12:41 mark, Mrs. Tucker (Joan Allen) and son were opening letters from customers interested in the Tucker Torpedo. Allen was identifying on a USA map where the letters came from, designated by a push pin. One letter was from Anchorage, AK and Allen put the pin in the inset map of Alaska. Alaska and Hawaii were not yet admitted to the Union in 1945, when the film takes place. They officially became states in 1959.

In the last scene crew members are clearly visible reflected in the red car.

During the early drive sequence which is supposed to be taking place in Ypsilanti, Michigan (700 feet above sea level), the California mountains can clearly be seen in the background.
