When Andy is playing with Woody at the beginning of the movie, he uses "RC" via his remote to launch Buzz out of a box. RC's remote was left on the road in the final chase scene of "Toy Story" and was not recovered.
When the toys ride the elevator to Al's apartment, they are on the elevator's roof. Yet as they jump off the elevator and run through the air vent, they exit the vent on the ground floor, not near the ceiling where they should be.
When the impostor Buzz is standing with the toys in the air duct preparing to charge into Al's apartment, his utility belt disappears for one shot, making him look like the regular Buzz Lightyear.
When Al is heading down the elevator, Buzz and the others lower Slinky towards the box that holds Woody. Woody is then pulled back into the box by the Prospector. However, earlier Al was seen stacking the toys into a perfect fitting box, it is not possible for the Prospector to have pulled Woody back into the box.
When Woody is being carried to Al's apartment by Al in a zipper bag, he peers out to see what is going on. To do so, he uses both arms to pull apart the two sides so he can see - however, at this point, his arm is ripped and therefore he could not have opened the bag like this (as in many previous and following shots a ripped arm is shown as completely useless to Woody, just hanging by his side).
When the toys see off the flight to Japan, they are overflown by plane coming in to land. The outbound flight would take off at the end of the runway; an inbound, landing plane would land at the other end, not at the spot the other took off from.
Al's plane has lights on in the cabin section prior to takeoff. All planes must have lights out before takeoff when it's dark at night.
At the airport, the plane to Japan takes off just seconds before another lands in its place. Takeoffs and landings would not be scheduled in this manner.
One of the baggage handlers says the rest of the luggage will have to go on the next flight. This would not be allowed in real life and doing so can result in disciplinary action as all luggage belonging to its particular owner must be on the same plane.
The semi with the large pipe on its trailer has the warning placard 1203. That is a hazmat sign for a truck carrying gasoline (a tanker, that is). Since a giant pipe isn't toxic, flammable, explosive, etc., it would be unlikely to display a hazmat placard at all.
In the first film, Sid burned a dot into Woody's head with a magnifying glass, but now the dot is gone. Since Andy adeptly sews up Woody's arm, it is possible that Andy (or his mother) touched up Woody's burn mark.
Zurg is seen breaking out of his package as the toys leave the store. As the first confrontation with the impostor Buzz states, all rangers are required to be in hyper-sleep for transfer, making it entirely possible that the toys can, in fact, move and be alive while inside their original packaging, therefore making it possible for Zurg to get free and also may be why Stinky Pete could move around if his box had indeed never been opened.
Toys in boxes do not become conscious until they are opened; this is seen in the first movie (when Buzz arrives), and in the toy store. Stinky Pete is in what appears to be an unopened box, but it has been opened. Presumably, doctoring the box to appear unopened was another job by the cleaner.
In the scene when Woody is having a dream about Andy returning from Cowboy Camp, Woody is dropped and falls into a garbage can full of broken toys. In all previous scenes, he was unable to use his arm after it tore, but uses both arms to attempt to escape the grip of the toys. However, as this is a dream it is quite acceptable that Woody would be able to use both arms.
In the outtake with characters from A Bug's Life, Heimlich is missing his butterfly wings. However, his appearance in this film is non-canon to said film, rendering it a moot point.
When Woody is rescuing Jessie from the plane, he extends his pull string to hook the ring on a bolt and swing to safety. However, after he unhooks the ring, none of his trademark sayings are heard as the string retracts.
As Woody first sees all the "Woody's Roundup" posters and records, one of the record covers that has Jessie and Woody playing instruments, uses the "and" twice together in the top text caption: "Saturday Morning's favorite Cowboy & and his pals join their musical talents to bring you...."
In the choice of viewing presentation screen on the DVD, the widescreen selection is shown in a 2.35:1 aspect ratio. This film was filmed in a 1.77:1 aspect ratio, not 2.35:1.
When the cargo door of the plane closes on Woody and Jessie, watch the bottom of the door. There is a rendering error as it passes through the conveyor belt.
When Buzz is using Mr. Spell to figure out what the 'LZTYBRN' on the license plate means, the 'B' and 'R' blocks have the exact same scuffs around the borders of the blocks.
A white truck has an airbag deploy when rear ending a green sedan from a low speed. The truck also appear's to be a 1979 Toyota Truck with Toyota not having airbags in the U.S. model until the 1995 Tacoma.
The cover of Life Magazine has a headline which reads "Sputnik - First Photos Revealed" and is dated 12 January 1957. Sputnik was not launched until 4 October 1957.
On the original 2000 DVD, the clip-on that plays before the Buzz Lightyear of Star Command movie trailer is "Coming soon to own on video and DVD." This movie was released on August 8, 2000, so the clip on should have been "Now available to own on video and DVD."
When Hamm is flipping through the channels, he goes too far and
says he needs to go around again. When he does, the commercial comes on and everyone says "Stop!" However, for about a second Hamm can still be seen clicking, but the channel does not change.
When Woody kicks the record player up to "78", the stylus moves far across the record, yet the song continues uninterrupted.
When Woody and Bullseye approach the sleeping Al to retrieve Woody's arm from Al's pocket, Al spills his bowl of cheese puffs all over the floor. A moment later, when Al is awoken by the television turning on, he jumps up from the couch and finds Woody on the floor, picks him up, and returns him to his display case. However, the crunching of Al stepping on the spilled cheese puffs is never heard.
When the impostor Buzz knocks over Woody in Al's apartment, the laser on his arm is heard without him pressing the button to activate it or the laser light being seen.
When Andy's toys and Utility Belt Buzz saw Zurg, they gasped before he arrived on the elevator.
When the toys steal the pizza truck, the truck has amber rear side markers. However, US-Spec requires vehicles have red rear side markers; amber rear side markers are Euro-Spec.
In the international release, when Buzz holds his heroic speech about having a friend in need and not giving up until Woody is back in Andy's room, the globe superimposed over him still shows the Soviet Union and even Germany divided into East and West despite the movie being produced well after the end of the Cold War.
Al is on a plane for Japan but the next morning he's on TV very sad in a chicken suit. The flight to Japan and back would take longer than this, not including the time it takes to produce and air a commercial.
After Andy's mom realizes that Woody somehow got downstairs and into Al McWhiggin's hands, she takes Woody and puts him in the cash box for safe keeping. After Al steals Woody, Andy's mom is never seen worrying or calling the police to report theft. Nor does she say anything to Andy (as Andy arrives home from cowboy camp all cheerful and eager to see Woody). It seems strange that she went through the entire length of the movie not knowing that Woody had been taken/stolen and didn't do anything about it. It's hard to believe that she didn't notice the wide-open cash box without Woody inside.
While Andy falsely assumes his mom bought Jessie and Bullseye, she never seems to question where they came from.
When a little girl pulled Woody's pull-string, his voice box said, "There's a snake in my boot!" But when Woody met Jessie, she pulled his pull-string, and the same phrase was repeated. In real life, the Sheriff Woody dolls shouldn't repeat the same phrases. First, they have to say different phrases. Afterward, they can repeat them.
Even though Al lost his luggage, the whole thing could had been avoided by simply taking his case with him on the plane, as his case can qualify for hand luggage.
Someone turns on the TV causing Al to wake up. Woody blames Jessie, but it was The Prospector who climbed out of his box to turn on the TV. However, Jessie did not see The Prospector who was nearby and in line of sight of her location.
For some unknown reason on the Toy Story 2 DVD Bonus Feature Cast of Characters Jim Varney as Slinky Dog is not mentioned.
When Mr. Potato Head tells Rex that "Woody's been shelved", he is seen plugging in his right ear, despite the fact that it has been attached the whole time. It was his left ear which Andy had removed moments before, as well as various other parts.
When the toys are running through the vent in Al's apartment, Utility Belt Buzz pressed down on his left arm to fire his laser and the sound is also heard. However his laser is on the right arm.
When Woody, Jessie and Bullseye dance on the record player, they seem to be powering it with their feet, as it speeds up and slows down following how fast they run. When Woody switches the speed to 78 RPM, the record accelerates by itself and the characters lose their balance. When they are ejected, the disc stops, establishing the record player was powered by the toys running on it. Changing the speed selector shouldn't have had any effect on how fast the record spins.
