Corrected entry: When Wall-E first finds the plant, he delicately places the plant with some dirt inside of the shoe. Later on in the film, when Wall-E is in free floating in space, he takes out the shoe to demonstrate to EVE that he has the plant. The dirt so delicately placed in the shoe would surely float freely in zero gravity.
Corrected entry: When Wall-E is sitting with Eve on top of his truck, in one scene he sits on the edge and plays with his treads. Listen to the pitches of the sounds he makes; he's using his treads to "play" the tune for "Put On Your Sunday Clothes".
Corrected entry: During one of the space scenes, Wall-E and Eve talk to each other. In space, there is no air. It is nothingness. Sound travels in vibrations through the air, therefore there cannot be sound in space.
Corrected entry: When Wall-E gets struck by lightning while holding an umbrella over EVE, watch his solar charge meter fill all the way up after the first strike.
Corrected entry: When the captain of the Axiom is first introduced, the camera pans across a series of previous captains, each increasing in their lack of fitness and therefore presumably representing a progression of all the captains since the Axiom first left Earth. Because only six captains are shown, service as captain would need to exceed 115 years each in order to span the voyage of the Axiom. Assuming one must be at least 20 before assuming command and one becomes no longer capable in the later 5 years of life, humans in this future would be living over 140 years. Physically fit persons might be able to do this, but it would be highly unlikely for such widespread lack of fitness to lend to such long life spans.
Corrected entry: When the Captain is doing the morning announcements, he states how it's the 255,642 day on the Axium making it the 700th anniversary. This can't be true since in 700 years (including leap years) there would be 255,675 days. And if they weren't including leap years (given that on a spaceship allowing for the earth's rotation wouldn't be necessary) there would be 255,500 days.
Corrected entry: The Zippo(C) lighter fluid would have evaporated and would not have ignited when attempting to light it.
Corrected entry: In the ship's waste room, there are countless massive piles of metal rubbish. Where is all that metal waste from? The sheer amount of it can't only be bits from broken robots/systems; since the waste is being compacted and released one big pile at a time, even 700 years worth of broken robot bits wouldn't amount to that mass with regular expulsion.
Corrected entry: When in the repair ward, a robot puts a load of make-up on Wall-E's face and then when he is in his 'cell', a Hoover-looking robot sneezes on him and the white powder is blasted all over his face. In the very next shot of Wall-E, the make-up is all gone.
Corrected entry: EVE stands for "Extra Terrestrial Vegetation Evaluator" but she is evaluating terrestrial vegetation. Unless she was designed before the Axiom left Earth, it would make more sense for her to be named TVE. However, she has a very sophisticated design, so it is unlikely she was designed that long ago. Her name doesn't make sense in accordance with her design, but it is much more pronounceable.
Corrected entry: During the final fight between the Captain and Auto, the ship gets tilted and all the occupants slide to one side. Assuming that the inside of the ship has some sort of artificial gravity (given that, when outside, Wall-E and Eve experiment weightlessness), the pull would always be perpendicular to the ship floor, independent of the tilt of the ship relative to an external observer. There is no "up" in space.
Corrected entry: At several points, Wall-E and Eve are speaking and making noises outside the Axiom. In reality, we shouldn't be able to hear anything.
Corrected entry: In the end, when it is panning out to the credits, the shorter building in the middle reads "Buy O Large" instead of "Buy N Large" or BNL, as it says during the rest of the movie.
Corrected entry: In several scenes where one of the characters is holding a cigarette lighter, the tip of the flame is rounded but the reflection on the robots shows the flame coming to a point.
