Corrected entry: The actual Kuiper Belt (where the Axiom is located) is just outside Saturn's orbit. However on WALL-E's space voyage, he passes another sun and another galaxy. That's not right.
Corrected entry: All satellites orbiting the earth experience a phenomenon known as "orbital decay" - the process of prolonged reduction in the height of a satellite's orbit. Larger satellites, like those shown in the movie, are especially susceptible to this as they collide with molecules in the outer atmosphere. The satellites depicted in the movie could not possibly have lasted over 700 years in orbit; the Skylab space station, for example, was only able to stay in orbit for six years before it crashed to earth.
Correction: Human technology presented here was able to create, among other things, a huge spaceship filled with a great number of humans over several centuries, with artificial gravity and a whole host of intelligent robots. Building satellites that are able to stay in orbit for a few centuries should be rather easy for them.
"Orbital decay" is the least of the problems here. Thrice throughout the film, we see a densely packed envelope of trashed satellites (which have lost the ability to fight orbital decay). The real threat to this envelope is called a "collisional cascade." The EVE's transport alone must have initiated one. At 0:33:34, we see the ship going through the envelope and... leaves it largely untouched. This is either magic or a movie mistake.
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: The Zippo(C) lighter fluid would have evaporated and would not have ignited when attempting to light it.
Correction: Since this movie takes place in the future and we have no idea what the fluid in the lighter is, this isn't a mistake.
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.
Correction: This is a common moviemaking technique. We all know that there is no sound in space, yet we need to know what the characters are (trying) to communicate.
Corrected entry: Battery in the "car-alarm" can't live 700 years.
Corrected entry: How do the Axiom and the robots run? Surely not solar power since they are in the Kuiper Belt with almost no sunlight. Not wind power. Nuclear power would require lots of water and getting rid of radioactive waste, with the possibility of a meltdown. How do they run?
Correction: Just because something isn't directly explained in the film, it doesn't make it a mistake, merely an unanswered question; try to learn the difference and submit in that section next time. There are all sorts of possibilities - controlled fusion reactions, Star Trek-style matter/anti-matter annihilation. We're talking technology a hundred years more advanced than our own, who knows what they might have come up with.
Corrected entry: When Wall-E is putting the spork on the shelves, you can see he has Rex, the green dinosaur from Toy Story, all covered in dust.
Correction: Having looked at the relevant shots closely, as I thought this sounded rather fun, I can't see him. Please provide additional information regarding his location in the scene.
There are two bowling pins on one of the shelves. You can see his head in between.
Correction: It's a very clear shot. He is between two bowling pins.
Corrected entry: The scooter that Skinner used in Ratatouille can be found in the trash pile early in the movie.
Correction: The entire opening third of the movie is set around piles of trash. If you're going to point out things of this nature, please take the time to make it clear exactly where this can be seen. "Early in the movie" is not remotely sufficient.
Correction: It's a very low chance that it is actually Skinner's scooter. There are probably hundreds of them amongst the rubbish.
Correction: This mistake is riddle with errors. First, the Kuiper belt is located out past Neptune, not just outside Saturn's Orbit. Second, the Axiom is shown next to a purple Nebula, which isn't the Kuiper belt. There isn't any reference in the film to say that the Axiom is located at the Kuiper belt either. Fourth, Considering the sequence of the voyage, it is our own sun the rocket passes, most likely using the slingshot technique to give it more speed. The Galaxy shown is also our milky way.
