Continuity mistake: When Andy plays with his toys, just before he goes to Cowboy Camp, in one shot Buzz rides off the scalectrix on RC, and hits Hamm, and RC flies over the bucket Hamm was standing on and goes way out of shot. Seconds later RC is now beside the bucket. (00:09:00)
Factual error: If the access hatch to the nose wheel well on an airliner was opened at any time during the take off run every alarm panel in the cockpit would light up like a Christmas tree. The pilot would immediately abort take off.
Other mistake: During one of the outtakes between Mr. and Mrs. Potato Head, Mrs. Potato Head packs a set of toy "teeth". In the DVD subtitles for this scene, it's printed as if she said "cheese".
Continuity mistake: In the scene where Woody slips off of Bullseye back in Al's apartment, After Jessie introduces him. Jessie comes along and tickles Woody. The word 'ANDY' is seen on the bottom of Woody's boot, This scene happens after Woody has been restored by the cleaner. In a scene later in the film, we see Woody scrape the paint away to reveal the word 'ANDY'. (01:02:00)
Deliberate mistake: Even though Hamm is flicking through the channels at the same speed, the side with Al's advert on it is visible for longer.
Plot hole: At the end when the gang get home to Andy's room, it's night time and the luggage trolley they drove home in is outside the neighbour's house. The next morning it's still there. But we see an ad with the 'chicken man' looking very sad because he lost Woody and the others. How could he have gone to Tokyo, realised the dolls were missing, then zoomed back to Tri County to do the ad the next day? While saving Woody, the toys explicitly say that Andy is returning home the following morning. They must have made it in one night, or they would have missed Andy's return.
Continuity mistake: Just before the other Buzz activates his anti gravity in the lift shaft, you can see that the lift is nowhere to be seen in the darkness, yet when Buzz and the other toys fall, they only fall a short distance before landing on the lift roof which is now highly illuminating the whole lift shaft. (01:00:00)
Deliberate mistake: The 'Life' magazine with Woody on the cover displays a smaller headline promising pictures of Sputnik, a clever reference to the fact that interest in space travel doomed the "Woody's Roundup" show. The only problem is the magazine's cover date is Jan. 12, 1957, and Sputnik didn't launch until October. Given the Soviet penchant for secrecy (no-one outside Russia knew about it until it launched), it's doubtful any photos of Sputnik of any kind would have been available to the American press nine months prior to the launch. This is a deliberate error on the part of the filmmakers - January 12 is director John Lasseter's birthday. (00:23:25)
Continuity mistake: When the Toys enter Al's Toy Barn looking for Woody, the colour of the tiles right after the cashiers don't match between the aerial and close-up angles.
Continuity mistake: Woody's height slightly changes in the scene where Buzz tries to convince him to return with them. You can notice that from the scene where Woody starts to explain why he doesn't want to come back, and in the one where he turns away and keeps his arms folded.
Continuity mistake: In the baggage area when Woody fights with Pete, his arm is torn (an injury which had previously rendered it useless). However, in the next scene going to rescue Jessie, he is using the arm freely and there is no sign of a tear or fix. There is then reference (and visible signs) later in the film that the arm has been fixed.
Factual error: Near the end of the film when Jessie and Woody escape the plane, Buzz and Bullseye stand on the runway. In the sky you can see a plane approaching and it passes just above them. A real plane can blow away an entire car when it's behind the engine, yet nothing happens to a bunch of toys.
Continuity mistake: With upgrades in animation the house Andy's family moved to at the end of the first film has undergone some slight changes. The house is still the same general shape, red in color and with the doors and windows in the same place. But the Toy Story 2 version gained an arch above the front door. Also, in the first movie the house was in front of some large pine trees, there was a straight path from the door to the street, and there was a wooden fence in the front yard. In Toy Story 2 the fence is gone, the path from the front door bends toward the driveway, and the pine trees behind the house are replaced by generic types of trees. The house also is much more detailed (as is most of the animation compared to the first movie), allowing the shading of the brick pattern to come in. (00:10:25)
Continuity mistake: At the beginning of the movie, Buster knocks over the Troikas (the toys that fit inside each other), but they vanish a couple of shots later. We can see that they aren't behind Buster when he sniffs the bedroom and heads near the Potato Heads.
Other mistake: In the elevator shaft, Buzz and the other toys react to Zurg riding the top of the elevator car before he's even visible.
Other mistake: When the toys are in Al's toy barn, Mr Potato Head and Rex are walking together and Rex is reading about how to defeat Zurg. Mr Potato Head takes his ears out, presumably so he doesn't have to listen to Rex going on and on. Hamm then comes round the corner behind them in the car and Mr Potato Head turns around. He wouldn't have heard the car coming if taking his ears out meant he couldn't hear. (00:43:16)
Other mistake: When Al gets off the lift on the floor where Woody is, the toys also get off the top of the lift onto what would be the floor above, but end up on the same floor.
Other mistake: In the last scene with the baggage plane, Woody, Buzz, etc. are all near the plane when it takes off. Since they were following a big jet, they are well down the runway once it takes off. Later, without them backtracking the runway, another plane passes overhead very close, as if to land. There is no chance to land a plane if it touches down that far down the runway. You will not be able to stop in time.
Revealing mistake: When the toys are watching Woody being stolen the games machine on top of the TV doesn't have its controllers plugged in, but Rex was playing earlier with a wire coming out of his controller, which clearly wasn't actually connected to anything.
Other mistake: When Hamm is pressing the remote control to get to Al's Toy Barn commercial, when he eventually lands on it, he still presses the remote several more times. The TV channel should have skipped the commercial again. (00:24:15)
Answer: It isn't Woody's holster that's blurred, it's his hand. And yes, the blurred effect is due to the video tape's degeneration.
