Corrected entry: In the opening scene, when the monster falls on the jacks, we see the door is less than half open. When the video is replayed, we see that the door is left more than half way open. (00:02:45 - 00:03:45)
Corrected entry: In the computer animation process, they make certain set pieces which can be used over and over again - when mike is being threatened with the 'scream remover' you can see that it is made up of canisters for screams, and various other parts, including half a door sorting frame for the main arm.
Correction: I don't think the convenience of repeating set pieces was a factor here: think of how many pieces needed to be made for the film. It makes more sense that Randall would build his secret machine out of parts available, such as the canisters and door frame. Still noteworthy however.
Corrected entry: When Mike and Sully are at the lockers and Mike puts in his contact, Randall slams Mike's locker, and that should have locked it, but Mike re-opens it with out re-entering the combination. (00:10:55)
Correction: Not all lockers immediately lock. In jr high school, our lockers could be shut without re-locking. You had to twist the dial as you left in order to lock the locker.
Corrected entry: When Sully and Mike first speak to the geeky monsters in the lobby, you can see a slug-like monster in the background just entering one of the corridors leading to the scarefloors. When Mike is talking to Celia a short time later, the same slug still has yet to enter the corridor.
Correction: They are similar, but, as stated elsewhere, there are certain common monster shapes that appear relatively frequently: slug-shape is one. Besides, the first slug has no lunchbox (judging from the movements of its right pseudopod) and the second one does.
Corrected entry: When Sully and Mike go back to work to take Boo back to her home, the clock on the wall as they enter says 8:50, a few minutes later Boo takes off and Mike and Sully go after her, a few minutes later Randell catches Mike and points to the clock which now reads 11:55. The chase only lasted a few minutes.
Correction: There are many clocks in the lobby of the power company, all over different hallways that lead to different scare floors and reading different times. This can be assumed to mean that the monsters recognize time zones (affirmed by the Eastern Seaboard lighting up during the first shift). The clock that reads 11:55 is "local time" for the monster world, but the other clocks refer to the human world.
Actually, the clock on the scare floor says 8:50 when Mike calls down the wrong door for Boo. That time must be for the monster world.
Corrected entry: When Mike goes to get the card to Boo's door from Roz, there is a clipboard slightly to her right on the counter. The shot switches to Mike's view and when it switches back to Roz's view, the clipboard has moved to the right even though Roz is perfectly still.
Correction: Yes, the clipboard is now hidden behind Roz's head, but that is because the second shot is from closer to her shoulder. The clipboard is still the same distance from the loose papers on the desk.
Corrected entry: The chef at Harryhausen's has a bandana with a Japanese symbol on it, and throughout the entire restaurant scene the symbol on the bandana changes.
Correction: In every shot the symbol is the same. I don't know what it means, but it looks like an inverted double cross over a short, pointed stroke and a snake shape.
Corrected entry: Just after the door is shredded, Mr. Waternoose or his assistant says something like "That's 56 doors this week. Kids just don't scare like they used to." 56 doors in a week is nothing when you consider that a kid is born roughly every 3 seconds - that works out at around 201,600 doors every week. Shredding 56 doors still leaves them with 201544 doors, which seems a lot more doors than they have monsters.
Correction: Waternoose isn't concerned about the total number of doors available - as seen later in the film, there are plenty back there to utilize - but rather about the RATE they are losing doors. A door here and there is not so bad, but 56 doors in a week could be the indicator of much worse things to come.
Corrected entry: The mobile Sully flushes down the toilet, when he thought Boo was toxic, is hanging above her bed when he takes her back towards the end.
Correction: There are two mobiles in Boo's room. The one that Sully flushed down the toilet is still gone at the end of the movie. The other one is still there.
Corrected entry: Just before they go into the scare room, a slug looking monster is mopping up a spill. When he is done, he leaves his own trail of sludge. When we see all of the scarers walking to their doors a little later, the slug is there, but the floor behind him stays clean.
Correction: It's a different slug-like monster. There are lots of them in the movie ("slug" must be a favorite body type in Monstropolis), and we see several between the time we see the janitor and the appearance of the scarers. None of them is the janitor (different color, fewer eyes, etc.).
Corrected entry: The Abominable Snowman tells Mike and Sully that the Himalayan village is 'a three day hike' down the mountain. However, after about two minutes of sledding/tumbling, Sully gets to within what looks to be less than a half-mile from it. Even more inexplicable, Mike was pretty much right behind him, judging by how quickly he finds Sully back at the factory.
Correction: Perhaps the Abominable Snowman was just trying to discourage Sulley from going to the village; he might not have thought it a good idea for Sulley to go back to the monster world.
Corrected entry: The scare total display board on the scarefloor wall shows the scarers with their photo and last name. There is one mistake. Randall's last name is Boggs but the display board says Randall.
Correction: Some people (or monsters, in this case) do prefer to be called by the surname (like Sulley) and others by their first name (like Randall).
Corrected entry: All the toilets in the Monsters Inc. men's room are in the size and shape familiar to us as being for human use. Yet only three or four of the monsters are close enough to humanoid form that would make the toilets accessible for sitting.
Correction: Possibly there are other men's rooms of different sizes to fit different monsters. After all we only see one restroom in the whole movie and of course there are others.
Corrected entry: When Sully and Waternoose are talking, Waternoose pours himself a cup of coffee. Just after Waternoose takes a sip, Sully demonstrates his scaring ability on him and he drops his cup. The sound we hear is of an empty cup hitting the floor, but didn't Waternoose just fill it with coffee? There should have been a splash type noise to indicate the coffee has spilt on the floor.
Correction: Look more carefully at the "coffee" - it isn't liquid, but thick, heavy sludge. Thus, if a cup of that stuff was dropped on the floor, we wouldn't hear any splashing.
Corrected entry: Why does Mike need to put in a contact lens after going to work? Surely if his eyesight is bad, then he would have needed to put one on before leaving the house. After all, he wanted to drive to work, supposedly with bad eyesight.
Correction: He could just need a corrective lens for reading, which he has to do for work.
Corrected entry: If Boo was the first child to enter the monster world, then how does the CDA know their detecting machines works?
Correction: The monsters regularly go into children's bedrooms, and could safely test their devices while the kids are asleep. It's not as if they've never seen a child before: they rely on them for power after all.
Corrected entry: When Randal is talking to Mike about making sure Boo goes back in her door at the lunch break look at which of Mike's hand is the hour hand. When Randal says "When the hour hand goes down..." he uses the wrong hand.
Correction: Randall does this on purpose- to hurt Mike and he actually says "When the big hand"
Corrected entry: When Boo is first discovered by Mike & Sully, they refer to Boo as 'it' and 'the child'. During the bathroom scene when Sully tells Mike that he named the child Boo, his exact words are "That's what I named her". There is no explanation why he switched the pronoun from 'it' to 'her'. For the rest of the movie, they do refer to Boo as 'her'.
Corrected entry: Why does Boo have a mobile? She sleeps on a bed and mobiles are for small babies in cribs.
Corrected entry: When Sully and Mike leave the company bathroom, they are walking down the hall and you can see that both of Mike's legs are wet. As they keep walking down the hall, they dry far too quickly.
Correction: Why do they? As far as you know, mike's skin can be like a lizard's or a snake's, therefore, the water slides off quite fast.
Correction: When the monster is on the ground spinning in circles, his feet hit the door closing it slightly.
