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.
