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.

In the not too distant future, humans have abandoned Earth because of the amount of rubbish. WALL-E, a compactor with habit of picking up everything he finds interesting, lives alone on the planet with a pet cockroach. He collects a variety of things, from a lightbulb to a VHS. He even has what appears to be the last plant. When an unknown aircraft comes to earth and drops EVE to look for a living organism WALL-E falls in love with her. WALL-E gives her his plant, which makes EVE go into a kind of sleep mode. When the spaceship comes to take EVE back, WALL-E decides to join her. What follows is an adventure onboard the Axiom, where the people of earth have moved to and now move on hovering chairs and get liquid food which they suck up through a straw. Due to laziness, they have become so obese that they are unable to move. Due to hastily given instructions given to it, auto, the autopilot it tries to get rid of the plant which compels WALL-E, EVE, the pilot and some malfunctioning robots to find a way to retrieve the plant and save the earth.

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.
More trivia for Wall-E
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.
