In 2005, Pixar were in the midst of a "conscious uncoupling" from Disney. However, Disney still contractually retained the rights to create sequels to any of Pixar's properties produced during their initial 7-year contract, albeit complying with Pixar's right of first refusal. The contested film in question? None other than Toy Story 3.
A proxy animation-house named Circle 7 Animation (derisively nicknamed "Pixaren't") was created in 2004 to helm this new project. Few details emerged regarding this incarnation of the film; only the plot to rescue a malfunctioning Buzz from being decommissioned at a Taiwanese recall factory. Well, the concept art for that version has surfaced just in time for the holidays, and they are terrifying.
