Trivia: Toward the end of the film, the toys are on a conveyor belt heading for the furnace and Lotso jumps off. At the moment when he grabs the wall rungs, the musical score for the next few seconds is taken from Monsters, Inc. when Sully and Mike are running through the hallways looking for Boo. Also when Andy is giving his toys to Bonnie and leaves it is plays the musical score from Monsters, Inc. when Sully and Mike had to say bye to Boo.
Trivia: Toy Story makes references to Star Wars episode IV, Toy Story 2 makes references to episode V, and this film makes references to episode VI. When Big Baby throws Lotso into the dumpster, this is reminiscent of when Darth Vader throws The Emperor off the platform, camera angles and everything. (01:15:00)
Trivia: The first two Toy Story films have received a perfect 100% rating on rottentomatoes.com. If Toy Story 3 had also achieved a perfect rating, it would have been the first movie trilogy in cinema history to do so. However, this film ended up with a 99% fresh rating, with two negative reviews.
Trivia: At one point in the film, Woody's voice box says the phrase "I'd like to join your posse, boys, but first I'm gonna sing a little song." This phrase has not yet been said by Woody's voice box in the final cut of any Toy Story film (until now), but it did exist as far back as Toy Story (1995) in a deleted scene where Sid tortures Buzz and Woody.
