Other mistake: The name of the actor who played Mike is given during the opening credits as Jordan Fry and during the end credits as Jordon Fry. (00:01:55 - 01:44:30)
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)
Continuity mistake: The tire track of the rightmost truck (in the top-down shot) is completely wrong. All 5 of the trucks were parked parallel. Besides, we can see only one pair of tire tracks per truck, but when a truck turns, the path the front wheels move on has a larger radius than the one the back ones move on thus creating two tracks. All this was OK just a shot before. (00:04:00)
Audio problem: In the scene where Veruca's Dad is explaining how she got the ticket, when the shot is pulled back, there is an echo. But when the camera is zoomed in, the echo is gone, as well as when Mr. Salt is talking and the camera is showing a flashback. (00:18:05)
Continuity mistake: In the scene where Violet and her mother are talking about the trophies, the trophies in the trophy cabinet behind them changes between the first shot and the second shot. (00:21:50)
Continuity mistake: 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. (00:41:35)
Continuity mistake: 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. (00:42:25)
Continuity mistake: After the boat ride, when the boat settles in front of the door to the Inventing Room, Charlie's hair is windswept from the ride. In the subsequent close-up scene, however, his hair is suddenly kempt again. (01:01:30)
Other mistake: 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. (01:15:05)
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)
Visible crew/equipment: In the Television Room, when Wonka is explaining how you will be home watching television, and a commercial pops up, and it wants you to try a Wonka bar (by reaching into the TV and getting it), you can see a cameraman standing behind the camera reflected in Wonka's glasses. It might be a little hard to see (try zooming in), but it's there. (01:27:40)
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. (01:38:25)
Other mistake: In the beginning of the song about Augustus Gloop, computer generated Oompa Loompas can be seen running through the Chocolate Room, preparing to sing their song. In the DVD release, some Oompa Loompas can be seen running to places that no real person could possibly stand on. This mistake was later corrected in the Blu-Ray release.
Other mistake: Squirrels are used in the factory to get nuts out of shells. Mr Wonka states that they tap the nut first to make sure it isn't a bad nut. However, this is never done until the action is pointed out.
Continuity mistake: 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.
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. Knowing that chocolate can melt around even the slightest heat, there is no way the candy would have survived the heat from the fireplace being just inches away.
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.
Continuity mistake: During Mike Teavee's scene, his father has some bits of hair overlapping the arms of his glasses. On the right side the bits appear and disappear from shot to shot.
Revealing mistake: 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.
Continuity mistake: 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.
Answer: We are never shown what happened to him but he may have gone to live with relatives or he was simply put into an orphanage.
