Trivia for
Monsters, Inc. (2001) More at IMDbPro »

• Bill Murray was considered and tested for the role of Sulley, but the director, Pete Docter, said that when the filmmakers decided to offer it to Murray, they were unable to make contact with him and took that to mean "no".
  
  
• The controls for the Monsters Inc. door mechanisms include a button that starts the process labeled "FIZT". At the time, Fiz-T was the latest software developed by Pixar Animation Studios to realistically render complex physical models - notably in this film to model Sulley's fur and Boo's clothing.
  
  
• Randall's original name was Ned.
  
  
• In the original draft of the script, Sulley was not be a scarer but a worker. Also Mike was Randall's assistant. In another draft, Sulley was Randall's assistant.
  
  
• Sulley's original name was Johnson and he had brown fur.
  
  
• The Abominable Snowman describes the children in the Himalayan village as "Tough kids, sissy kids, kids who climb on rocks", a line taken from an old jingle for Armour hot dogs.
  
  
• There are retro Disneyland posters in the Monstropolis travel store and some of the children's bedrooms.
  
  
• The restaurant that Mike and Celia are at is called the Harryhausen. This is an homage to Ray Harryhausen, the man who made the stop-motion animation monsters for films like Jason and the Argonauts (1963). Also, the octopus behind the bar in the restaurant with only six legs is a reference to It Came from Beneath the Sea (1955), a film in which Harryhausen created an octopus with six arms due to budget restrictions.
  
  
• The Hidden Cafe is the name of a real restaurant in the San Francisco area which had been a favorite with Pixar's animators, including director Pete Docter, since the early '90s.
  
  
• Pete's Barber Shop is named for director Pete Docter.
  
  
• Disney/Pixar prepared a special trailer for Monsters Inc. to show before Harry Potter and the Sorcerer's Stone (2001). Mike and Sulley play a game of charades in their apartment, with Sulley acting out "Harry Potter." Mike has difficulty solving the puzzle, some of his guesses being "Dirty Harry", "Harry Flowerpot" and "When Hairy met Sulley," (a reference to Billy Crystal's starring role in When Harry Met Sally... (1989)). Eventually Sulley puts on round spectacles, sticks a paper lightning bolt to his forehead and sits on a broom with an owl on his arm, to which Mike ecstatically guesses "The Sound of Music". Sully gives up and walks offscreen as Mike finally guesses "Harry Potter" and the cut away to title cards noting that "Monsters Inc." is "Now showing at a theater near you. Really near you. Like, maybe, right next door." At the end of the trailer, it is Mike's turn to act out a part, with a very bored looking Sully guessing it is "Star Wars" within seconds, much to Mike's dismay.
  
  
• The original teaser (where Mike and Sulley enter a room in "Outer Magnolia" instead of Outer Mongolia) was also specially made and features material which did not appear in the film. The scene from the trailer where Sulley tucks Boo into bed and says, "Don't worry, I'll protect you," does not feature in the film, either.
  
  
• 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. The actress who provided the voice of Boo is Mary Gibbs.
  
  
• News leaked in early fall of 2001 that this movie would feature the first teaser for Star Wars: Episode II - Attack of the Clones (2002). Hundreds of Star Wars fans paid admission for the movie just to see the teaser and reportedly some left after seeing it.
  
  
• This is the fourth movie to feature both John Goodman and Steve Buscemi and is the first of the four not to be directed and produced by Joel Coen and Ethan Coen.
  
  
• The famous computer graphic of "The Teapot" can be seen on the table in Boo's room.
  
  
• In the background where the blob monster falls into a sidewalk grate, there is an art store called "Gallerie du Dominique". This store is named after Dominique Louis, an art director at Pixar.
  
  
• On the scare floor leader board, the name immediately below Sullivan and Randall is Ranft, a reference to longtime Pixar writer Joe Ranft.
  
  
• At Harryhausen's Sushi Restaurant, employees shout, "Get a paper bag!" whenever somebody walks through the door. In Japan, it is customary for employees of any store to shout "irasshaimase!" (pronounced ee-rah-shai-mah-seh"). The monsters shouting, "Get a paper bag!" is a phonetic reference to this fact. There's a similar Japanese reference in Toy Story 2 (1999) (see Trivia).
  
  
• After Sulley says goodbye to Boo, he closes the closet door. When Boo jumps out of bed, she has grown 7% by the time she reaches the door. The programmers had to do this as she was too short.
  
  
• John Goodman and Billy Crystal sometimes recorded their lines in the same room together, an unusual move for animated films, where actors more often work alone. Steve Buscemi and Frank Oz (Randall and his assistant Fungus) also recorded their lines together for the bathroom scene.
  
  
• The ingredient list on the cereal that Sulley feeds Boo is as follows: Tentacles (includes suckers), sugar pods, gelatin, artificial flavor, artificial color (Yellow 53 & 54, Red 400, Blue 21, Plaid 16, Puce 30), salt, seawater, naturally occurring mercury, barium, sulfuric acid, lead, bile, blood, sweat, tears, zinc oxide, vitamins D & F, anemone, brine shrimp, coral, plankton, deadly pufferfish, depleted uranium (to preserve freshness).
  
  
• In the simulated bedroom used for training, the letters of the alphabet can be seen as a border at the top of the walls. For some reason, the letter J is backwards.
  
  
• Towards the end of the movie, Mike opens a package with a magazine featuring Sulley and Mike on the cover. On the back is a full page advertisement for a computer system with tagline at the bottom "Scare Different..." Meanwhile, the new slogan "Think funny" appears all over the scare floor after the change in the corporation. These are both nods to Steve Jobs, CEO of Pixar and Apple (which had the "Think Different" ads).
  
  
• 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.
  
  
• About 3:26 into the movie, when the simulation is 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 which reads "510-752-3000", which is Pixar's phone number.
  
  
• All of the digital displays in Monstropolis (Sulley's clock radio, scare station consoles, "Days Without An Accident" sign) are nixie tubes, a neon digital display technology from the 1960s.
  
  
• George Sanderson (the monster who keeps getting caught by the CDA for "2319" emergencies) is the monster who was supposed to be the protagonist for the original Monsters, Inc. concept - a bumbling, inept monster who couldn't scare anyone, 'til a timid girl, put upon by her brothers, teaches him how to be scary. George in the final version is even the same color and monster type in the original storyboards.
  
  
• In an early draft, Sulley was supposed to be a lowly helper. In fact, a quite long storyboard had been made of this original plot as shown in the DVD.
  
  
• Sulley's big armchair in his apartment has a hole in the back to let his tail through.
  
  
• The three ads at the end of the company play, "Put That Thing Back Where It Came From, Or So Help Me!" are for Tony's Grossery (seen earlier in the movie when Mike and Sulley pass it), Pixar Shorts ("We've got the important things covered") and Pete's Barber Shop (specializing in/selling Claw Wax, Scale Polish, and Mange Management).
  
  
• It normally took 11 to 12 hours to render a single frame of Sulley because of his 2.3 million individually animated hair strands (Total number of hairs: 2,320,413).
  
  
• The animators considered giving Sulley tentacles instead of legs at one point, and glasses at another. However, they decided to use legs because they believed the audience would concentrate more on the tentacles than Sulley's face. They also considered making Mike arm-less with only legs.
  
  
• According to the original character design sketches found on the DVD, Fungus's first name is Jeff and his surname was originally "Frungus".
  
  
• When Sulley and Mike are walking to work and pass "Tony's Grossery", the items on sale include Mangle Fruit, Bilge Berries, and Blood Oranges (a real kind of orange).
  
  
• In keeping with the running gag of Mike being obscured in every photo, on the DVD the hole in the disc appears directly over where Mike would be standing.
  
  
• In the German dubbing of the film, the Abominable Snowman speaks the Swabian dialect, which is mostly spoken in south-western Germany, and makes a reference to wishing he had banished to the Swabian Alb where he has friends.
  
  
• The newspaper article concerning Boo's appearance in Harryhausen restaurant, though briefly seen, is actually readable and fully written in complete English.
  
  
• Mary Gibbs 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.
  
  
• The design of Mike is based on a Halloween costume inventor Doug Malewicki designed for his daughter Michelle, which was featured on an edition of "Pee-wee's Playhouse" (1986).
  
  
• Bob Peterson, the movie's story supervisor, provided the temporary voice of Roz, the green secretary, during production. The nasal, sing-song voice proved to be such a success that they kept it in the final film.
  
  
• Boo's teddy bear is the same bear as the one seen on the shelf in the simulator bedroom.
  
  
• The monsters have drawn the letter "J" backwards on the alphabet banner in the simulation room.
  
  
• '2319' might reference to the 23rd and 19th letter in the alphabet: WS. WS may stand for White Sock, because a white sock is the first alien object to be destroyed by the CDA.
  
  
• When shown theatrically, the film was preceded by the Pixar short For the Birds (2000). The short also appears on home video reissues of the film. Additionally, the home video releases include a short entitled Mike's New Car (2002) (V) featuring characters from the film.
  
  

• SPOILER: When Sulley is about to say goodbye to Boo, Boo is trying to get him to play. A doll of Nemo The Clownfish appears. This is the first appearance of the character who will be the focus of Finding Nemo (2003), storyboarded before this movie but not completed until two years later.
  
  
• SPOILER: Randall Boggs is last seen in a trailer home. There is a Pizza Planet truck from Toy Story (1995) and Toy Story 2 (1999) beside the trailer, and the trailer and Pizza Planet truck were also featured in A Bug's Life (1998). In fact, the man inside the trailer is actually the simulated boy from the first scene. The mom is the same boy but with a "bun" placed on his head.
  
  
• SPOILER: In the ending sequence when the monsters make children laugh instead of cry, one monster on the factory floor can be seen carrying a sledgehammer and a watermelon - a clear homage to the comedian Gallagher, who popularized that particular gag.
