Other mistake: This is a small error with the UK release of the film. For reasons that Disney have not disclosed, the film was renamed to "Zootropolis" and has had almost every mention of the word "Zootopia" both vocally and visually changed. However, just before Judy is interviewed you see the camera pan over the reporters and Chief Bogo. If you look on the floor it says "pia" as in "Zootopia." It is clear that this texture was not changed to say "Zootropolis" due to its placement, as it would have involved rendering the whole scene again just for this word change.
Other mistake: Maui's hook is shaped in such a way that it would be impossible for him to pry the heart from TeFiti as it is depicted in the opening sequence.
