Factual error: In the scene in the glass elevator, when Mike Teavee wants to push a button, he presses the TV Room button. The elevator stops going down and immediately moves horizontally. The characters within the elevator are thrown against the wall from the sudden change. However, they are thrown against the wall that is in the direction the elevator is now moving, instead of the opposite wall as they should have been. (01:20:15)
Factual error: In the scene where Wonka is flashing back to his childhood, he finds a chocolate that fell beneath the fire grate in the ash. He opens it and eats it unscathed.

Factual error: When Augustus is caught in the tube, chocolate sprays out from a leaky connection. The tube was under a vacuum and the bottom end was open to the river below, so pressure could not build up either above or below him.
Factual error: Dusseldorf does not, nor has it ever, looked like the quaint place shown in the film. The caption does get quite a laugh from German audiences, though. The place shown is the town of Gengenbach.
Factual error: In the intro the chocolate wrapper states that the bar weighs 7 oz net, yet the boxes the bars are packaged in says 150g. 7oz is approximately 200g. (00:03:00)
Answer: Wonka is simply uncomfortable around people. Gum chewing is simply an annoyance he never had to put up with as a recluse.
