Trivia: At the beginning of the film, when Buzz is battling his way into Zurg's fortress, he has to jump onto several floating discs to get to the (battery) power source. He jumps onto five discs before they collapse under him; each plays a note, the first five notes of the theme from "2001: A Space Odyssey".
Trivia: In the scene where Potato Head is driving the toy car down the aisles of the Toy Barn (after Buzz and the gang split up) and Rex suddenly places the Buzz Lightyear strategy guide in front of his face, if you pause you can see the price for the guide: $4.95 U.S., $50.00 CAN. A little joke on the money exchange between the two countries.
Trivia: During the scene in the toy store, the toys use a car to get around, in which Rex at some point falls off and starts running after them to catch up. Mr. Potato Head spots him in the mirror with the words "Objects in mirror are closer than they appear." written. This is a parody of a scene from the original Jurassic Park movie, where the island visitors tries to escape a T-Rex in the same manner.
