Continuity mistake: When Po is trying to get into the ceremony at the beginning of the film, the fireworks attached to his chair explode and leave him with dirty white fur. After he clears the gate and gets inside to the ceremony his white fur is completely clean again.
Continuity mistake: When Wall-E presents Eve with the plant, he is facing her directly. When Eve is later viewing the footage from her security camera, Wall-E is shown facing at an angle towards the left of the screen, instead of straight ahead.
Other mistake: When Fry and Colleen are lying in bed, his hand is around her shoulder but it is the same colour of Colleen's skin. (00:04:25)
Continuity mistake: Penny pours dog food onto a bowl for Bolt and places it next a pillow. Cut to Penny trying to get Bolt to play with his toys and a bone design has appeared on the bowl. It's too fast for Penny to turn the bowl around. (00:16:35)
Continuity mistake: When R2-D2 closes the door to the platform in the back of the monastery (before Asajj attacks Ahsoka), Asajj stabs both of her lightsabers through the door, a few inches apart from each other, and starts moving them downward. In the next shot, on the other side of the door, there is already a solid line (the top of the circle) cut into the door. There wasn't enough time for her to have stopped and connected the space between the two holes. (00:45:40)
