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.
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.
Continuity mistake: When EVE leaves the line-up and is followed by Wall-E, he does not leave a dirt path, though before and after this scene he does. (00:37:20)
Other mistake: On the ship, Wall-E leaves dirtmarks everywhere, except when he's hiding behind an EVA pod. (00:37:20)
Continuity mistake: After the escape pod scene (but before the 'dance'), Wall-E uses a fire extinguisher to fly back and forth. Between every camera shot except one, all the extinguisher particles disappear instantly. (00:56:50)
Continuity mistake: When EVE is reactivated on the Axiom bridge, she 'sits up' on her transport bed. The camera shot changes and she's 'standing' well in front of the bed rather than on it or even right next to it. (00:44:50)
Continuity mistake: When Eve fires a shot at the tanker they show an overhead view of the scene - there are three other tankers sitting on the starboard side of the exploded tanker. When the tankers fall like dominoes there are now four of them next to the exploded tanker.
Suggested correction: There is correct number of ships, but more likely wrong ship is burning in second image.
Continuity mistake: When Wall-e is climbing the ladder on the space ship, he climbs nearly to the top. Then he is knocked down from the force of the take-off. Then in the next shot, he is back at the top. (00:31:40)
Continuity mistake: The sky over Wall-E's city is totally covered, from horizon to horizon, with thick brown clouds. When the Earth is seen from space at the beginning of the film, there is no such cloud cover anywhere on the planet. It looks more like the old Universal Studios logo than the actual Earth. The clouds appear out of nowhere as the camera zooms down. (00:01:30)
Continuity mistake: In the scene where Eve meets the cockroach and Wall-E, after blowing up the tires Eve approaches Wall-E. We get a shot from Wall-E looking down Eve's gun, and her eyes are squinted and challenging. The shot changes to the side so the cockroach can jump to Wall-E, and her eyes are softer and more neutral- then the shot changes back to looking down the gun and they're challenging again. (00:18:30)
Continuity mistake: When the capsule is counting down to self destruct, it says 10 seconds twice. Two seconds apart. (00:56:10)
Continuity mistake: The ramp to Wall-E's home has got ridged slots, however, in some shots the slope is completely smooth.
Continuity mistake: When Eve repairs Wall-E, you can see some tread segments are popped out, but when Wall-E powers back up they're all good as new. She doesn't replace his treads, just some gears.
Suggested correction: However, even if the treads are not changed, the wheels inside the treads are, which could well straighten up his treads.
Continuity mistake: When EVE is heading to the holo-detector with Wall-E and MO, Auto tilts the ship/alters the gravity field so that everyone on board (basically the entire human race) slides across the lido deck and piles up on the starboard bulkhead. When Captain McCrea takes control and rights the ship everyone is still piled against the bulkhead, with just a few people falling off the pile and some attempting to walk for the first time. Five seconds later when tossing the plant to EVE and going into hyper jump everyone on the ship is now equally distributed across the entire lido deck area. (01:19:10)
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)
Continuity mistake: When Wall-E places the Rubik's Cube down, the position of it changes to when he sorts the spork out. Notice the colours that are visible on the corners. (00:07:05)
Factual error: When AUTO tilts the Axiom during the argument with the captain, which later results in WALL-E being crushed and everyone sliding to one side, should not be possible. In space, there is no gravity, and on the Axiom there is artificial gravity, meaning everything is pulled inward, so if the ship turns, they shouldn't notice and nothing should change.
Character mistake: Captain McCrea tells the passengers that it's the 700th anniversary of the Axiom's first flight. The Axiom has been in flight for 255,642 days. Actually, 700 years is 255,675 days. That figure includes the additional day in 175 leap years.
Suggested correction: Leap years only occur because of the earth's rotation around the sun. As the AXIOM is in space, there is no need to correct for the earth's rotation.
First, rotation is the spin of the Earth (which cause day and night). Revolution is the earth orbiting the sun (which causes years). However, this correction is not valid on the premise you're trying to present. Many films set in space still use Earth time, so a day is 24-hours, even though they're in space and there is no sunrise and sunset (although it's stated the Axiom operates on a 25-hour day). So they would use Earth's year, which takes 365.256 days. Since the Axiom isn't orbiting the Sun, it wouldn't experience a year, so they're using something else. The fact that they're slightly off suggests it's a writing mistake and there's no evidence they use an arbitrary 365.203 day year.
That's still wrong. Even if their years were strictly 365 days, 700 years would be 255,500 days, not 255,642.
Continuity mistake: We see Wall-E chucking stuff into his cooler. The items inside the cooler are constantly changing position. Most noticeable is the rubber duck. (00:11:00)
Continuity mistake: All the makeup that Wall-E has put on him in the repair bay disappears instantly. (00:51:00)
Suggested correction: Simply untrue. At 00:52:43, WALL-E receives a cute make-up. At 00:52:54, WALL-E shakes off its fake eyelashes. At 00:52:57, a suction machine sprays white soap over WALL-E, who activates its wipers (screenshot's top pane). By 00:53:06, WALL-E's face has lost much soap but is still stained. At 00:53:17, WALL-E is clean again, but the suction robot is busy sucking WALL-E's soap (screenshot's bottom pane).
