Corrected entry: When Sully, Boo, and Mike are riding the door and Boo screams, only one door is activated. When she laughs in the same scene, every single door is activated. Near the end of the movie it is revealed that laughter is 10X more powerful than screams. In that case, only 10 doors should have been activated from her laugh.
Corrected entry: The monster that operates the doors for Randall, has legs that bend back like a bird's, but in the shot when Sulley saves Mike from the scream-extractor and puts that monster where Mike was, he is sitting down and his legs bend forward. (00:14:00 - 00:54:05)
Corrected entry: Mike uses a microphone to magnify his voice when doing his comedian bit with the kid at the end of the movie. You'd think the kid's parents would hear him. After all, near the end of the film Randall is teleported through a door to a trailer home, and the kid complains to his Maw that another 'gator has got in - and Maw not only sees and hears Randall, she belts him with a shovel - so she (or the shovel.) can feel him, too.
Corrected entry: When the "scarers" arrive for work in the "Right Stuff" scene, Pauley has no eyes. He is to Sully's left (the right of the screen as you look at it). His assistant then puts his eyeballs in to prepare him for scaring. Later, after work, even after the monsters have left the locker room and are heading out of the Monsters Inc. factory for the evening, Pauley has all of his eyeballs left in. (00:13:30 - 00:20:15)
Corrected entry: When Mike and Sulley are stuck in the Himalayas with the Yeti, the Yeti says that you can get milk from a Yak. This is not true as the Yak is the male of the species and the female (which would produce milk) is actually a Nak.
Corrected entry: When Mike and Sully first come to the work, you can see two big monsters who talk near the reception, but Cilia is not there. But when they come closer, she is there.
Corrected entry: Did you notice that Mike's mum looks like Roz? When they're doing the concert in the credits, after they do the play, Mike says, "What a night for my mother to be in the crowd", and you'll see Mike's mum.
Corrected entry: One of my favorite parts in the movie: When you first see Roz, she is reading "The Glob." Look closely at the headlines - they are hilarious. For example, "Baby Born With Five Heads - Parents Thrilled".
Corrected entry: When Mike and Sulley are falling through the door vault, they escape through the door they are holding onto. When the door hits the ground, it completely shatters, including the metal frame that surrounds the door. No matter how hard that door hit the ground, the frame wouldn't have broken like wood.Brad
Corrected entry: Around the end of the movie, Sully has Boo activate all the doors so that they can get to Boo's door. However, having activated most doors around the world (some have been destroyed), there is no mention of anyone from the human world trying to access their closet, and coming upon the factory. We know that the doors work on both sides, as this is how Sully and co. get around from one location to the other.
Corrected entry: Near the end when Mike, Sully and Boo enter the factory on the back of door and the CDA's and Waternoose are waiting for them, Mike throws one of Boo's socks at a CDA, then runs off. When Sully and Boo come out from the behind the door Boo has both socks on. Later when Boo is returned to her room you can see the missing sock. (01:11:35 - 01:16:50)panda
Corrected entry: Throughout the movie there are times when monsters prefer cleanliness and times when they prefer dirtiness. Examples of monsters preferring cleanliness include Sulley brushing his teeth at the beginning of the film (Mike says "Fight that plaque.") and a little later on at 'Monsters Inc' when a green slug monster mops the floor. Examples of monsters preferring dirtiness include Roz reading a newspaper with an article at the back of it that says 'Gain pounds' and when Mike asks Sulley for oderant (smelly garbage, old dumpster, low tide, wet dog).
Corrected entry: When Mike tries to put the blame on Waxford he says that he works at station six. Waxford actually works on station nine which can be seen when they line themselves up the first day.
