Directed by John Lasseter, starring John Ratzenberger, Laurie Metcalf, Tim Allen, Tom Hanks, Wallace Shawn, Annie Potts, Don Rickles, Jim Varney
Continuity: When Buzz drops into the van through the sunroof (at the gas station) he has a dead fly stuck to his helmet shield. Woody attempts to pull it off and clean the glass, but doesn't finish the job as there is still some goo on the glass where the fly was. On the following shot the glass is completely clean.
Continuity: Buzz, while pushing the tool box off of the blue basket Woody is in, stretches to about 3 times the length he normally could from that position. When he first starts pushing against the window sill with his feet, he stretches out fully a few seconds later, about half the length of Sid's desk. He continues to push the box over and says "Almost there..." before he does and we can see he still has his feet on the window sill. Most people will have to watch it for a better understanding.
Deliberate "mistake": When Buzz Lightyear demonstrates his "flying" abilities in front of the other toys, his right wing would have clipped the car track. Submitted by Dr Wilson
Other: It's been mentioned that Sid sets his clock for 8:25 and it goes off at 7:00. Here's some more errors for Sid's crazy clock physics. When Woody is saying "Psst" to Buzz from inside the blue plastic basket, the clock on the wall says 6:25, yet the alarm clock next to Buzz says 6:55. It goes off 5 minutes later and after Sid takes Buzz out of the room, the clock on the wall has changed to 3:10. When Woody is talking to Sid's toys a minute later, the clock now reads 10:00. The maximum amount of time that passed between the already wrong 3:10 and the 10:00 is 5 minutes. You can tell because Sid wanted to launch Buzz strapped to the rocket ASAP and Woody wanted to rescue Buzz from his current strapped-to-a-rocket state very fast.
Continuity: When Woody and Buzz are at the gas station and the big truck pulls in, Woody falls limp to the ground. The truck pulls over him, and stops with its tires an inch from his head. In fact, the brim of Woody's hat sticks up into the space between the two tires. In the next shot when Woody scrambles out from beneath the tires, his head is directly under the tire to our right.
Continuity: Just before Sid blows up the Combat Carl figure, he throws a cement block at the figure, just missing it. Then we see him lighting the explosive on Carl and then he blows up. When we cut back to a wide shot of Sid's garden, the block has been moved to the other side of the garden, nowhere near where it landed before Sid lit the explosive.
Continuity: At 4min. 19sec. into Chapter 5, when the army soldiers are yelling into the baby monitor that the kids are heading up to Andy's room, the baby monitor is right in front of Woody on the floor. Yet, when the camera pans out to show all the toys scrambling for their places (4min. 21sec. into Chapter 5) the monitor is gone, and the piggy bank is right in front of Woody. Then, when the camera zooms back in to show Woody (4min. 24sec. into Chapter 5), the baby monitor has reappeared.
