Other mistake: After the magnet grabs Slink during the incinerator scene, all the toys grab metal objects to avoid getting torn up. Afterward, they all let go of their metal objects to drop down. However, Slink also drops down despite not holding on to anything because he is made of metal.
Suggested correction: Or, the other toys helped him down.
Continuity mistake: During Andy's daydream at the beginning of the film, Mr. Potato Head has an eye patch over his left eye. When the daydream cuts back to reality we see that Andy has removed Mr. Potato Head's left eye to symbolize the eye patch. But when Andy's mum comes in with the video camera, his left eye is suddenly back in. (00:01:15 - 00:05:25)
Ken: And this... Well, this is where I live. It's got a disco, it's got a dune buggy, and a whole room just for trying on clothes.
Trivia: At the Sunnyside Day Care there is a wooden version of Lighting McQueen rolling around on the floor. In the sandbox is the Luxor Ball, the yellow ball with the red star and blue stripe. There is also the Pizza Planet truck.
