Corrected entry: When Augustus Gloop's parents are interviewed, the father eats the end of the microphone, but the announcer goes on to ask the mother a question with the mic still intact.
Corrected entry: In the Chocolate Room, there are several see-through pipes coming out of the chocolate. The chocolate is supposed to be being sucked upwards in all of them. However, in some of the pipes it is actually flowing downwards, since it was easier for the film-makers to only pump it upwards in some of them and then send it into the other pipes to go back down. This is confirmed when Augustus Gloop gets stuck in one of the up-pipes - there is no chocolate at all flowing in one of the down-pipes while he is stuck in there.
Corrected entry: At Wonka's factory gates (coming from his entrance door towards the gates on the right) there's a road traffic sign which states '(you are on a) priority road' on the road is bending to the left. I presume the set (gates, carpets, office) was build on an existing junction.
Corrected entry: When everybody moved to the side of the boat to exit onto the dock, the boat should have leaned in that direction from the imbalance, but it stayed steady.
Corrected entry: In the scene where Mike TeeVee is made smaller and transmitted through the tv, he's on a black stage. When he talks to his mother, she's obviously on a movie type screen.
Corrected entry: In the half-room, Wonka angrily tells Charlie and Grandpa that there is no lifetime supply of chocolate due to stealing fizzy-lifting drinks and touching the fan which needs to be 'washed and sterilized.' But how did Wonka actually KNOW that Charlie and Grandpa did the above, since they were alone at all times and there were no Oompa-Loompas or CCTV cameras watching them? Also, when Charlie and Grandpa rejoin Wonka and the others, Wonka is carrying on without any suspicion whatsoever and he doesn't question them till they get to the half-room.
Corrected entry: In the 'half room', half a wall clock is shown, yet the pendulum mechanism is not directly below the 6, it is slightly offset to the right.
Corrected entry: When Charlie and Grandpa enter the 'half-room' to enquire about the lifetime supply of chocolate, look at the 'half-lamp' on Wonka's desk. It has a full complete light bulb. This bulb should be 'in half' to match the rest of the room.
Corrected entry: What was stopping the children from giving an Everlasting Gobstopper to the *real* Slugworth? I'm sure he'd be very interested in them.
Corrected entry: When Violet turns into a blueberry, her belt bursts off, but a few seconds later as the Oompa-Loompas start singing her belt has disappeared from the ground.
Corrected entry: When Augustus Gloop falls in the chocolate River, Charlie grabs a lolly and Augustus holds it. As he does this, it bends.
Corrected entry: In the scene where Mike TV gets turned into a million pieces and reappears in the television, he has his goggles on when he gets transported and his goggles are not over his eyes when he reappears in the TV.
Corrected entry: When Wonka is walking along the path along the red carpet, when he falls forwards to do his trick, you clearly see the straw as a bump under the carpet, to soften his fall.
