Continuity mistake: When Augustus falls into the chocolate river, Wonka's right hand is resting on the top of his cane, which is planted in the ground, but the next shot shows his right arm up, and bent at the elbow.
Scott215Continuity mistake: When Veruca throws the golden wrap at Wonka, the table holding the wrapper is head-on to the viewer, implying Wonka's point of view, but after Veruca throws the wrapper on Wonka, the table is off screen and 90° to the left of Wonka and the other factory guests.
Scott215Continuity mistake: In the "I Want it Now" musical number, Veruca grabs some golden egg wrapper and throws it on Wonka. When she does, the table with the wrapping is immediately behind her, but when the scene cuts to her after she has thrown the wrapper on Wonka, the table has disappeared.
Scott215Continuity mistake: When the guests enters Wonka's Fizzy Lifting room, Veruca Salt and Mike Teevee are standing next to each other, when Mike turns away from Veruca and takes a step. The next shot shows them both close together again.

Chosen answer: He felt that it took too many liberties with the story. In the original agreement, Dahl himself was to write the screenplay (he was, by that point, a not-unsuccessful screenwriter), only to find that his version of the script was subsequently heavily re-written, including what Dahl felt were a number of unnecessary gimmicks, such as Wonka's penchant for literary quotations. Even the title of the film was changed from the original "Charlie and the Chocolate Factory", in order to tie into the launch of the "Wonka Bar", a new candy bar made by the Quaker Oats company, who co-financed the film. Annoyed at all the changes, he ultimately disowned the film and refused to sell the cinematic rights to the sequel, "Charlie and the Great Glass Elevator".
