Continuity mistake: During the Golden Gate Bridge crash sequence, a reversed shot of a life-sized 1972 Trans-Am braking hard is shown. The next shot shows a model car smashing into a model school bus, and the car is suddenly a 1965 Corvette. The fimakers have painted it red & white so it resembles the Trans Am.

Revealing mistake: In the final shot of the destruction of Krypton several of the people falling into the abyss disappear a split second before the shot of Krypton exploding.
