Other mistake: During the Oompa Loompas' first number (Augustus Gloop), the lyrics are animated on the screen - but one word doesn't match. The song line is "What are you at getting terribly fat"; the words on-screen read "WHERE are you at."
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.
Other mistake: In the scene where the newscaster is about to announce that the first gold ticket has been found, he walks over to a map of the world. Take a look at the northwest corner of the US. There is a big blue dot just to the right of Idaho that cuts through Montana and covers half of Wyoming. The dot is where the newscaster will later hang the number three marker.
Other mistake: During the glass elevator ride, first Joe points out their house can be seen but then when the area is shown on camera, no little house like theirs is in the shot. Next, Charlie says he sees his school, and again when the shot looks down below, no school at all is seen, but rather just streets that come together through a small tunnel and random houses.
Suggested correction: When the Wonkamobile and passengers are covered in lather, it goes through a magical "squeegee" line that instantly has everyone clean and dry. Perhaps the same principle goes for the paddlewheel.
The paddles would not come out looking so "pristine".
