- The tone of the movie in general can be very unnerving for some to watch. The first half comprising zero spoken dialogue save for the robots' occasional Pokémon Speak and the odd pre-recorded ad that echos in the distance is extremely bleak. As beautiful as the scenery is, it's a relief to find genuine, living humans still alive aboard the ship in the second half.
- AUTO's reaction to the Captain preparing to set the Axiom on course to return to Earth: Throughout the whole movie, AUTO has spoken in a curt, quick Machine Monotone, but when it becomes clear the Captain is set on taking the plant himself...Captain McCrea: AUTO, EVE found the plant. Fire up the Holo-Detector.Captain McCrea: You know what? I should do it myself. (Starts rolling his hoverchair towards the elevator.)AUTO: (In an unusually stern tone) CAPTAIN. (AUTO zips over to block the Captain's way to the elevator) SIR. I INSIST YOU GIVE ME THE PLANT.Captain McCrea: AUTO, get out of my way.AUTO: WE CANNOT GO HOME.
- For that matter, the reveal of what protocol A113 actually is: With the efforts to clean up Earth's garbage failing and toxicity levels still rising, Buy-N-Large ultimately gave up on their efforts of ever getting humanity back home and determined that life on Earth had become unsustainable. The A113 protocol announcement video sent to the BnL autopilots is pretty much one big Apocalyptic Log: The video is damaged and glitching out, the crew can barely be bothered to even open the video with the BnL jingle, and BnL CEO Shelby Forthwright himself has gone from a peppy, Sharp-Dressed Man to a broken disheveled mess, complete with a gas mask hanging from his neck to wear once he wraps the video up because of how horribly toxic the air has become. Doubles as a Tear Jerker.
- Pay close attention to the portraits of the previous Axiom captains. AUTO starts off in the background, but slowly gets closer and closer over time, until he is staring right over the current captain's shoulder. All this time, AUTO was the true captain of the Axiom; the human captains were merely figureheads.
- They're also getting fatter... which is kind of fair given their environment, but also a bit disturbing.
- Then while the current captain is realizing the above, Auto slowy slinks down right behind his shoulder, closer than ever.
- WALLE getting tasered by AUTO when he refuses to hand over the plant. It comes completely out of nowhere.
- The climax with the Axiom tilting, with several helpless screaming people sliding towards the wall. It culminates with one of the people mover trams sliding from its track and nearly crushing the passengers, before EVE barely manages to hold it up to save them. Meanwhile, AUTO turns the Holo-detector off. As it sinks back into the floor, WALL-E desperately tries to hold it up, but AUTO electrocutes the Holo-detector button, causing it to slam down and crush WALL-E.
- After the Captain shuts down AUTO and rights the Axiom, EVE rushes toward the holo-detector to pry it open and free WALL-E, but it won't budge. After eventually placing the plant in the holo detector, WALL-E rolls out, severely damaged.
