Other mistake: On the ship, Wall-E leaves dirtmarks everywhere, except when he's hiding behind an EVA pod. (00:37:20)
Other mistake: When Eve repairs Wall-E, she uses a jack to push him back into shape, putting it in one side, and separating it. Then she slides it to the other side. The jack collapses instantly as she slides it; if jacks collapsed that easily they wouldn't be very useful. The sort of jack she uses doesn't have a release mechanism either. (01:22:30)
Factual error: As a trash compactor Wall-E does not function logically. When he fills his chest compartment with garbage and runs his internal compactor, the cube that exits his body is the same volume as the trash he puts in, despite that trash having been compacted. He does not add extra trash to fill the empty space after running the compactor - there are three scenes that show him filling up only once with loose garbage and then ejecting a densely compacted cube. (00:02:30)
Suggested correction: You haven't noticed the exact shape of his body. The back sticks out a tad. Garbage fills the space and the back pushes in to compress it.
Question: How could Auto act against his directive? He's playing the top-secret order he got (never to come back to Earth) in front of the captain, yet isn't able to act against it again because things might have changed in the 700 years since the order was received. And in the face of the new evidence (the plant), doesn't that contradict the order?
Answer: One of the key points of the movie is that programming can evolve - WALL-E being the most obvious case in point. After all this time, Auto's entitled to be somewhat erratic in how he deals with things. Besides, he's still very firm on his primary directive, to prevent the return to humanity to Earth - keeping the existence of that directive a secret is rather less critical. As for the plant, that does very little to invalidate the directive. It may show that the principles underlying that directive are flawed, but Auto's not got the leeway to deal with that. The directive still stands.
