Visible crew/equipment: There is a cameraman shooting near the gate of Wonka's factory: he is strategically placed to get up close shots shown in the movie yet he blends in to the crowd to make the movie audience think he is one of the many media technicians filming the event of Wonka opening his factory. Later, when the guests are passing through the gate, the cameraman has disappeared.
Other mistake: When the boat that Willy Wonka and the passengers are riding on is heading for the tunnel through the river of chocolate, two crewmen are cranking the paddle wheel. The wheel is in an opening in the middle of the deck. As the paddle is rotating, moving the boat through the river, the blades are always clean and dry and never have any chocolate on them whatsoever. Also the paddle is rotating the wrong way. It should be rotating clockwise.
Corrected entry: How come Charlie didn't get any publicity after he found his golden ticket? Everyone else did.
Correction: Actually, Charlie did get some publicity, as Wonka tells Charlie he read about him in the papers.
Correction: Because he found his ticket the day before the tour, there was not enough time for publicity.
After buying a regular Wonka bar and finding the last golden ticket, a woman comes up and pulls Charlie to a group of people and announces loudly that he found it. There could have been enough time from the moment the crowd of people saw Charlie with the golden ticket to Charlie making it home for someone to get the information.
Factual error: In every version of the story, including the book, in the scene where Augustus Gloop is sucked into the chocolate pipe, there's no pressure below him (it's an open river, with the pipe sticking into it) so the pressure must come from a vacuum at the top of the pipe. Augustus would have had his lungs and innards sucked out until he was thin enough to pass through the pipe. He would not have survived.
Suggested correction: In the book Charlie ask Mr. Wonka if all the other kids would be all right and he tells him yes they will.
This isn't a valid correction because the point of the mistake is that he wouldn't survive, as shown. At best you're saying Wonka lied to Charlie.
Suggested correction: The Cameraman is part of the news crew that was filming the event all around. Not a mistake.
The point being is that the cameramen in the crowd are part of Director Mel Stuart's film crew, getting angles and footage of the crowd for the movie without hiring additional crews to get the same shots.
