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 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.
Trivia: "A113" is the code for AUTO's directive to stop the humans returning to earth. This is a reference to the classroom at the California Institute of the Arts where character animation is taught and is placed in films as an inside joke by many alumni of the course, appearing, for example, in every Pixar film to date. A fuller list of appearances can be found here. (01:05:00)
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.

Continuity mistake: When picked up from Earth, Eve is placed into the first of five spaces (left). When unloaded on Axiom, it's the fifth on the right. (00:32:59 - 00:36:29)
