Casting Gag: In Hindsight. Pixar didn't realize that they actually cast the voice of the Spanish Buzz toy for Spanish Buzz until after the fact.
Genius Bonus: Potato Head using a Tortilla and a Cucumber while his body was trapped. Unless you're a vintage toy collector, you might not know that was how Mr. Potato Heads were actually sold: They were originally only a collection of parts meant to be used with real vegetables, and were later sold with plastic bodies to discourage food wastage.
Troubled Production: When Pixar started on this film, they thought could save some time just using their old computer files of the main characters from the previous film. Unfortunately, when they tried, they found out that they neglected to keep them updated with their current operating system and thus were inaccessible for use and the animators had to remake the characters from scratch.
What Could Have Been: Due to Pixar not renewing its seven-film distribution deal with Disney in 2004 that would also give the latter full rights to its properties and sequel production, Toy Story 3 was intended to be produced by a newly established studio called Circle 7 Animation, along with sequels to Monsters, Inc. and Finding Nemo. It was to have a very different plot involving Buzz getting shipped back to Taiwan as part of a worldwide recall, and Woody and other toys meeting up with some "misfits" along the way. With the deal falling through in January 2006, and then-CEO Michael Eisner being succeeded by Bob Iger, Disney would purchase Pixar and give creative control back to them, giving us the sequel we all know and love, along with Monsters University and soon-to-be Finding Dory. Circle 7 would be shut down two months later,m with most of the animators going to either the feature animation department or Disneytoon Studios.
