Several new vehicles in the film, including police cars, display California dealer license plates.
For one song, Charlie is lit with a spotlight obviously mounted above even though the scene is supposed to be in a carnival tent.
When Freddy takes Charlie's challenge to hit the target twice in a row at the dunk tank Freddy disputes the first throw so they start again. On the first throw of the re-start you hear the sound of a hit and the girl is dunked but you can see that the ball never really hits the target.
