Revealing mistake: When Violet turns blue, in any shot facing her back you can see the blue light source used at the very left of the frame (widescreen only). (01:12:24)
Visible crew/equipment: In the invention room, Veruca's dad talks to Wonka. The camera gets close to them. On the bottom of the frame is either a shadow of the camera or the boom mic.
Continuity mistake: When WIlly Wonka is talking to Mrs Teevee about Loompaland (at the "Mr Wonka I am a teacher of Geography", "Oh good then you'll know all about it" part), the rear shot of Mrs Teevee shows Mr Beauregarde proceed to eat a giant sweet of some sort. But in the next shot he has the sweet at waist height.

Continuity mistake: When Charlie gives his pay to his mom, Grandparents George and Georgina are asleep but their head still change from lying at an angle to straight as the shots change.
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".
