Zootopia (partially found pre-rewrite version of CGI animated film; early 2010s)
Zootopia (also known as Zootropolis in some countries) is a 2016 animated film produced by Walt Disney Studios. The film received critical acclaim for its subject matter and well-written characters, but according to directors Byron Howard and Rich Moore, the film underwent a significant rewrite during production. Footage from the pre-rewrite version is crudely animated, and most scenes never made it past the storyboard stage. A full script of this version has not yet been released.
In the original script, all the predators in Zootopia were required to wear "Tame Collars" that would deliver an electric shock if the predator became aggressive. Nick Wilde would open an amusement park called "Wild Times" where predators could have their collars removed. Fearing that the predators would have their collars removed permanently, the city would send Judy Hopps to investigate Wild Times and close it down.
