Continuity: In the scene when Agustus Gloop gets sucked into the chocolate tube, the inside of the tube is covered in chocolate. But in the far away shot, when you see the tube being retracted, it is perfectly clean inside and out.

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.

Visible crew/equipment: When Charlie is shining Willy's shoes near the end, you can see the reflection of a crewman in Willy's glasses when he glances to his right.

Continuity: At the beginning of the movie, the Golden Tickets are placed over the upside-down chocolate bars, meaning that the tickets are actually on the bottom, but later when the children find the tickets, they are now on top of the bars.

Continuity: During the scene in the chocolate room, Violet's mother has red, sticky candy all over her teeth and face, visible when she smiles at Mr. Salt. A few seconds later, all of it is gone.

Continuity: When Veruca is choosing a squirrel, she heads for the last one in line, furthest from the ladder. Then after it cuts away and back, she is headed towards the middle of the line, but then she is headed for the last one again. When the squirrels jump her, she is about 1/4 of the way down the line, starting from the ladder.

Continuity: During Mike Teavee's scene, his father has some hair bits overlapping the arms of his glasses. On the right side the bits appear and disappear from shot to shot.

Continuity: Willy Wonka is bobbing his head to the Oompaloompa song in the nut room. But when the shot pans out, he is perfectly still.

Continuity: In the scene where Mike Teavee has smashed up the red pumpkin-looking thing, he smashes it cleanly into two or three quite big pieces. When his father says "Mike, please" the pieces behind him are much smaller and all over.

Continuity: Veruca's lollipop disappears when she gets into the boat.

Continuity: When Charlie's grandfather gives him money so he can buy another Wonka bar, the coin changes position in his hand between shots as the camera cuts from Charlie's POV to his grandfather's. The "heads" side faces Charlie first, but then it's facing his grandfather when the camera switches. Unless it's a two-headed (and therefore fake) coin, that's impossible.

Continuity: At the nut factory, when Mr. Salt is there with the ladies, and he is walking up to the podium, the microphone is facing towards where he is walking from. Then in the next shot when he is at the podium facing the ladies, the mic changes direction and is centered, facing him.

Continuity: When the factory gates open for the contest winners, the shadows in the courtyard change between shots. [This is a reference to the first film in which the shadows shift a lot. It is also shown in other parodies of the original film, eg, the Family guy episode "Wasted talent". Still a valid mistake.]

Continuity: On Charlie's birthday night he breaks up the chocolate bar into pieces and gives them to his family, when he gives a piece to his father the piece is in two pieces but when his father starts eating it, it is in one piece.

Continuity: When Mike Teavee has been sent by television, Wonka is pointing to the screen when the camera is showing outside the screen, but a split second later, when the camera is showing inside the screen, both of Wonka's hands are leaning on his cane.

Revealing: When Augustus is leaving the factory, he is wearing a brown colored glove on the hand he gnaws on. You can see the seams in the glove.

Factual error: In the scene where Augustus Gloop gets stuck in the pipe from the chocolate river, there are two shots that show the pressure in the pipe is too great and one of the seals of the pipe burst out some chocolate. This could not happen because the machine on the ceiling sucks the chocolate up. In order for the pressure to build up underneath Augustus for the seals to burst there would need to be a machine in the river pushing the chocolate up.

Deliberate "mistake": Duesseldorf 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.

Continuity: When in the Chocolate Room, Mike Teavee crushes the pumpkin into three pieces. It then zooms out and shows him crushing it into three pieces again when Mr. Teavee comes up.

Other: When seen from inside the trash chute in the nut sorting room, the Oompa Loompas could not have leaned over the hole as far as they did. Other views during the same scene show they had to stay back a fair distance due to the curve in the floor.
