When Al packs the toys into the case, notice that he packs Woody on the left, Prospector on the right. In two later scenes, however, the left-right relationship is reversed...
- When Slinky Dog is hanging inside the elevator trying to pull Woody out of the case, Prospector rises from the *left* (Woody's old position) and pushes Woody back down into the *right* side of the case (Prospector's old position).
- The same switch happens in the airport baggage transport scene. After Prospector punches Buzz, Woody rises from the right side of the case.
Also notice that in both of those scenes, you never see Prospector's open box as he interacts with the other characters. This is especially noticeable in the first of the two scenes. After pushing Woody back into place, Prospector just drops back in as the case shuts. He wouldn't be able to do that unless his box were open, and yet there's no lid visible in the shot.
