Monsters Inc. is arguably one of Pixar's best movies with the possible exceptions of The Incredibles, Toy Story, and Toy Story 2. (No, TS3, you didn't make the cut!) But as I was browsing on the internet, I ran across an article that gave out some interesting trivia about Monsters Inc. and I thought I'd share it with all of my wonderful readers out there.

1) Randall's scaring assistant Fungus shares the same voice actor as Yoda

Frank Oz is almost as legendary of a voice actor as Kevin Conroy, Mark Hamill, or Clancy Brown. He's done everything from Star Wars to Sesame Street and he's done an outstanding job at all of them!

2) Boo's real name is Mary


Let's just be honest here, Boo is just about the most adorable animated kid ever. She is nicknamed "Boo" because she loves to hide and then surprise the monsters by shouting "BOO!" at them. Sulley, (whom she nicknames "Kitty") takes quite a shine to the human girl while Mike's only concern is returning her to the human world where she belongs. Boo's real name is actually Mary, although to my knowledge, this fact is never referenced in the actual film.

3) Sulley is a hairy beast

Sulley is one giant mass of purple and blue hair. But did you know that he actually has 2,320,413 individual hairs?! Fun fact: the animators used the same technology to create Sulley's hair as they did to make the sea anemone in Finding Nemo, but they had to invert the process because Sulley's hair is pulled down by gravity while the sea anemone's fronds are floating up in the water.

4) The film's sushi restaurant is named for a stop-motion pioneer

Ray Harryhausen was one of the earliest animators to experiment with stop-motion techniques, and as a tribute to him, the name of the Monsters Inc. sushi restaurant is Harryhausen's.

5) 90% of the monsters in the movie have the same tongue

According to the Disney animators, rather than spending hundreds of manhours and thousands more dollars to give each monster a unique tongue, the majority of them (including protagonist Mike Wazowski) have the same rounded greenish-yellow tongue, which is something I had never noticed but I will never forget when watching the movie.

6) Roz the receptionist is voiced by Dug from Up

You never saw that coming, did you? Roz, the grumpy paperwork-hounding receptionist from Monsters Inc. is actually not only voiced by a man, but by the same man who plays Dug in Up. The loveable, hyperactive canine couldn't be more opposite from Roz, but Bob Peterson crushes it in both roles! SQUIRREL!

7) How many doors does the Monsters Inc. vault actually have?

The Door Vault is a pretty amazing piece of equipment. It's got literally 5.7 MILLION doors in it! Now, I'm no expert, but I'm willing to say that it took a big team a long time to draw 5,700,000 doors. Fun fact here: my house has way fewer doors than this place!

8) Boo's room is an Easter Egg treasure chest!

Boo, like any other girl her age, loves her Disney Princesses, as evidenced by the fact that her toy chest has a Jasmine doll sticking out of it. The ball next to her bed is the "Luxo Ball", which is the ball used in the Pixar opening sequence that shows the company's lamp mascot Luxo Jr. jumping on it. In other shots of her room, Nemo from Finding Nemo and Jessie the Cowgirl from Toy Story 2 and Toy Story 3 are also visible. Way to go on your blatant product placement, Disney.

The big question is, how much of this did you already know?


Did you know all of these facts or were there some surprises?
