Monster’s Inc. Fun Facts & Easter Eggs

Sharing is caring!

Remember the monster under your bed or in your closet as a kid? Monsters Inc. shows us that those monsters were just doing their job. Go inside the Monster World and see how scaring kids works and what happens when a kid sneaks inside their world. Here are some Monsters Inc fun facts and Easter Eggs.

Monsters Inc. Movie Fun Facts

What is Boo’s Real Name?

Boo’s real name is Mary, as shown briefly on one of the crayon drawings she shows to Sulley in the scene where Boo is going to sleep on Sulley’s bed.

How Old is Boo?

In early drafts, the character of Boo was written to be six years old. The writers decided to make Boo younger because it would make her more dependent on Sulley. She is two years old in the movie.

The Movie Tells Us Pixar’s Phone Number

About 3:26 into the movie, when the simulation has ended and the monster reaches for a knob on the control panel to review the videotape, just below and to the left of the knob is a little indicator that reads “510-752-3000”, which is Pixar’s phone number.

How Hairy is Sully?

It normally took 11 to 12 hours to render a single frame of Sully because of his 2.3 million individually animated hair strands (Total number of hairs: 2,320,413).

How Did Pixar Get Boo’s Voice Recorded?

Mary Gibbs, who plays Boo, was so young that it proved difficult to get her to stand in the recording studio and act her lines. Instead, they simply followed her around with a microphone and cut Boo’s lines together from the things she said while she played.

What Does 2319 Mean?

The 2319 code is for a white sock incident. The 23rd letter in the alphabet is a W and the 19th is an S, meaning the code actually stands for W.S. (White Sock).

Monster’s Inc Easter Eggs

An Easter Egg in movies is a nod to another movie in a movie. Pixar always gives a nod to the next Pixar movie, which in this case was Finding Nemo.

  • In the first scene, one of the toys on the boy’s bedroom shelf is the toy plane that hung from the ceiling and caused Buzz to “fly” in.
  • You can also see the Luxo ball (the Pixar ball) in Boo’s Room and Boo hands Sulley a Jesse doll and a Nemo toy.
  • As Mike and Sully go through the scare floor, the rolling clown, from Toy Story can be seen in the background.
  • When Randall is practicing camouflaging into backgrounds of walls, one of the images given to him is the wallpaper Andy had in his room.
  • John Ratzenberger plays a small part in every Pixar movie. In Monsters Inc he plays The Abominable Snowman who has been banished to the Himalayas.
  • The Pizza Planet Truck makes its way into every Pixar movie and in Monsters Inc. it is next to the trailer Randall gets trapped in. The trailer also makes an appearance in A Bug’s Life.
  • You can spot the red unicycle from the Pixar short Red’s Dream during the final scene — Red’s Dream was Pixar’s second computer-animated short.

I enjoyed the article and was going to save it for future reading...until I looked at your bio (again) and found out you believe in a stupid fan theory known as "The Pixar Theory". Let me just point out to you for a moment what should be an obvious fact: The whole thing is just wrong and has never once been confirmed by any of the animators working in the studio. Also, the recent releases of "Toy Story 4" followed by "Onward" were supposed to debunk and destroy the theory altogether--as we can clearly both hear about with Second Chance Antiques in the "Toy Story 4" commentary, and also tell by the two moons in the sky for "Onward". Jon Negroni has no business continuing to profit off his stupid fan theory (Especially in book form!) and SuperCarlinBrothers also has no business telling de-bunkers like me that "there is no disproving of it", because continuing to add in every single new release just doesn't really improve anything. Instead, this action just makes the entire theory more stupid altogether. Just because there are Easter eggs hidden in these films, doesn't automatically connect them in a single universe altogether--it's more of a multi-verse is what it is. Plus the theory only exists to ruin childhoods, so just keep that in mind the next time you go back and re-read those dark-sounding details that make the movies sound horribly depressing: I'm not joking about this one. It's time to stop accepting fan theories as canon or fact, because they're clearly fan-fiction.

I think the theory adds a fun element to the movies I love. To each his own, have a great day!
