"We Scare Because We Care"

Monsters, Inc. is the fourth feature film of Pixar. It was released in theatres on November 2, 2001, and re-released in 3D on December 19, 2012.[3] A prequel to the film, Monsters University, was released on June 21, 2013.


Set in an alternate dimension run by monsters, Monsters Inc. features monsters working in the Monsters, Inc. factory where monsters enter the Human World to scare children so their screams can power the Monster World. However, when a human girl named Boo enters their world, top scarer James P. Sullivan and his assistant, Mike Wazowski, must return her.


Monsters, Inc. is set in Monstropolis, a city inhabited by monsters, some of whom are those who emerge from bedroom closets to scare human children. This is used to collect the screams of kids, which power the city. The main power company in the city is called Monsters, Inc. The Chairman and Chief Executive CEO is a crab-like monster, Henry J. Waternoose. The top scarer at Monsters, Inc. is James P. Sullivan, a blue-furred monster (with purple spots) who is partnered with the green, one-eyed Mike Wazowski.

The two of them are best friends and roommates. Sulley is a gentle and easy-going creature, while Mike is obsessed with his vehicle and dreams of marrying his future girlfriend, the Medusa-like Celia Mae. Sulley's main rival as a scarer is the gecko-like Randall Boggs who possesses the ability to change the color of himself to blend into his background, like an actual gecko.

As the two train and head off to work, their discussion reveals that the city is suffering a scream shortage because children have become desensitized to fear by an over-exposure to television. After they arrive at the Monsters, Inc. work floor, it is shown that monsters can call up and travel through any child's door, thus being able to sneak in to bedrooms around the world and collect screams. In order to allow Mike to take out his girlfriend, Sulley agrees to stay at work late and turn in his paperwork. He finds a lone door on the work floor after hours, a violation of policy.

An investigation leads to a small human girl coming through into the monster world. Sulley is frightened, as it is believed all human children are toxic to monsters. After three attempts to put her back, he attempts to take the girl to Mike, who is enjoying a romantic dinner with his girlfriend at Harryhausen's. The girl escapes and is seen, causing mass panic and alerting the Child Detection Agency (CDA). The two grab her and barely make it home.


The girl stays overnight and is soon named Boo (for her habit of saying "Boo!" all the time). The two come to know she is not dangerous as once thought, but they still plan to return her home the next day. She is disguised as a monster and they sneak her inside Monsters, Inc. Mike wants to toss her in any old door, but Sulley wants to return her to her home. A mistake gets Mike kidnapped by Randall, who had intended to take Boo. Randall has created a machine to extract screams straight from kidnapped kids. Sulley and Mike tell everything to Waternoose. However, it turns out that Waternoose is in on Randall's scheme. Because of the decline in productivity, he fears for the company's future, and sees Randall's machine as the only way of ensuring Monsters Inc's survival. Waternoose betrays them, banishing the two to the Himalayas.

The two stay with the Yeti until Sulley learns of a village down below. After an argument with Mike, he sneaks back to the monster world that way. Mike soon follows. They confront Randall and attempt to rescue Boo. In the end, Mike and Sulley send Randall to a motor home in a Louisiana swamp which was also seen in A Bug's Life, where he is beaten senseless with a shovel by the family living inside (who mistake him for an alligator). Mike and Sulley destroy the door Randall went through, thus trapping him.

Mike and Sulley trick Waternoose into exposing himself to the CDA, whose true leader is Roz, the scare floor secretary. Boo is sent home and her door is put through a door grinder. Sulley comes to realize that laughter is more powerful than screams and the company is redefined. Sulley becomes the new Chairman and CEO, and the monsters now enter the doors to entertain the kids as comedians, resulting in ample energy for the monster world. In secret, Mike also has Boo's door reassembled. Sulley takes one more peek inside and Boo is heard but not seen, while Sulley has a surprised and happy smile on his face.



The idea for Monsters, Inc. started with a lunch in 1994. At this lunch was John Lasseter, Pete Docter, Andrew Stanton, and Joe Ranft. One of the ideas that came out of the brainstorming session was a movie about monsters. Docter started working on the script in 1996 and with Harley Jessup, Jill Culton, and Jeff Pidgeon completed a draft treatment in February, 1997. The initial story did not have the character of Mike Wazowski. He wasn't added until a story review meeting between Pixar and Disney in April of 1998. The movie went into production in 2000.[4]

Particularly challenging in the production process was the rendering and animation of Sulley's hair. Each of the more than 2 million hairs on his body was required to move independently, collect snow particulates, react to wind, bounce around when he moved, and cast shadows on the other hairs. Obviously, this would be impossible for animators to do efficiently by hand, so Pixar set up a new simulation department that would develop computer programs to automatically mimic real-world physics in animation. It took a long time to make these tools reliable, and for the longest time any degree of realism in Sulley's hair was not possible. They are still far from easy to use. One exceptionally bad early test (an animation of Sulley clumsily trying to navigating an obstacle course) resulted in the hairs stretching, going through objects, sticking to the floor, and glitching out. These tools were eventually brought to the point of being workable (if imperfect), and were adapted to work on Boo's clothing. Pixar continues to add capabilities to these tools to the present day.

The Himalayan scenes were also particularly tricky. The Abominable Snowman's cave didn't have a clearly defined ceiling, floor, and set of walls, so the lighting team had considerable difficulty getting the shadows in this scene to look right. Sulley's sled ride and subsequent wipeout were probably the most difficult scenes in the entire movie, requiring the hair simulators to be finished and perfected before the snow particles could be brought into the mix.

The release of Monsters, Inc. was almost delayed by a lawsuit brought by Lori Madrid against Pixar, Disney and Chronicle Books. The suit alleged the defendants had stolen her story There's a Boy in My Closet, which she had mailed out in October 1999 to a number of publishers, including Chronicle Books. The plaintiffs had requested a temporary injunction against the release of the film. Judge Clarence Brimmer, Jr. had a hearing on the injunction on November 1, 2001, the day before the movie was to be released. He judged against the injunction, and the entire suit was thrown out on June, 26, 2002.[4]


The film was given a 96% on the Rotten Tomatoes review site, saying it's not as sophisticated as the Toy Story series but a fun film for children of all ages.

Attached Short Films[]

For the Birds[]

The theatrical and video/DVD release of the film included For the Birds, a Pixar short made in 2000, a year before this film was released.

Mike's New Car[]

The video/DVD release also includes Mike's New Car, a short starring Mike and Sulley.

Partysaurus Rex[]

Partysaurus Rex was included on the Blu-ray re-release of Monsters, Inc.[5]

Alternative Versions[]

One month after the movie's theatrical release (on December 7, 2001) a version with alternative end credits was brought into theaters. There, the credits are accompanied by a "blooper reel", followed by the musical "Put That Thing Back Where it Came From or So Help Me", performed by the cast. This version can be found as a separate feature on the collector's Edition DVD and in the credits of the VHS and 4:3 full-screen DVD versions as well as the end credits of the R2-R5 widescreen version for Eastern Europe. As is common for Pixar movies, international versions differ in the contents. Many English inscriptions are either removed or replaced by more generic symbols, especially in Monstropolis and at the Scare-floor. For instance, the "Stalk/Don't Stalk" traffic light is replaced by a green two-headed monster (for "Stalk") and a forbidding red hand (for "Don't Stalk"). Additionally, an animation of Sulley telling Boo to go to sleep was changed for Non-English version, as in the US version, he holds up two fingers to illustrate "to" in "You - go - to - sleep". For the title sequence, language versions that do not use the Latin Alphabet replace the letters "W" "A" "L" T" "D" "I" "S" "N" "E" "Y" "P" "I" "C" "T" "U" "R" "E" "S" with eyeballs peeking out the doors. Several European DVDs contain only the "international" version, whereas the US DVDs and US/UK VHS and Blu-ray contain the "US" version. Some of the examples for alternative angles can be seen in the bonus material of the 2-Disc DVD and Blu-ray of the film.

The film was re-released in theaters in 3D on December 19, 2012, and it featured the outtakes in 3D during the credits just like the movie.

There is a parody of Monsters, Inc. in the Cartoon Network show, MAD. It is called "Poké-monsters, Inc." and involves Ash Ketchum being released in the monster world rather than Boo.


Pixar confirmed a prequel to the film, which was released on June 21, 2013.

3D Re-release Details[]

The conversion to 3D made sense to producers and developers especially considering the extensive scenes in the movie involving unending moving doors. Joshua Hollander and Bob Whitehill, along with a team of 14 pros spent a year continuously recreating the world, characters, and story into 3D. Pete Doctor, the director, mentions that the film was always thought of in 3D and that the transition was easy. Doctor insists the movie will be comfortable to watch (no strain), consistent (enhancing, not changing), and captivating (immersive). Each scene was taken in and re-shot, determine how much of the 3D effect was necessary and when to hold back for dramatic effect.

Some problems arose with certain images throughout the movie when converting to 3D: for example, there is a scene in the movie with paintings that have no 3D information to proces; these problems had to be reworked from scratch. Sulley's hair was also problematic as each hair had to be randomly generated when it came to 3D movement; they had to make it as close as possible, but could not replicate it.


  • A manga version of Monsters, Inc. was produced by Hiromi Yamafuji and distributed in Kodansha's Comic Bon Bon magazine in Japan; the manga is published in English by TOKYOPOP.
  • Feld Entertainment toured a Monsters, Inc. edition of their Disney on Ice skating tour.

Theme park attractions[]

Monsters, Inc. has inspired three attractions at Walt Disney theme parks.

  • In 2006, "Monsters, Inc. Mike & Sulley to the Rescue!" opened at Disney's California Adventure at the Disneyland Resort in Anaheim, California. The dark ride was developed to boost the theme park's lagging attendance, and was quite successful in doing so, at least for a period of time.
  • In 2007, "Monsters, Inc. Laugh Floor" opened at the Magic Kingdom at the Walt Disney World Resort in Lake Buena Vista, Florida. The show is improvisational in nature, and features the opportunity for guests to interact with the monster comedians, and even submit jokes of their own via text message. [6]
  • In 2009, "Monsters, Inc: Ride And Go Seek" opened at Tokyo Disneyland at the Tokyo Disney Resort in Chiba, Japan. Following the format of the California dark ride, "Ride and Go Seek" is an extended version with enhanced effects.

One Pixar tradition is to create trailers for their films that do not contain footage from the released film. Trailers for this film include:

  • Sulley and Mike stumble into the wrong bedroom, after Mike misreads Mongolia as Magnolia. Sulley berates Mike for making the mistake, possibly due to his lack of knowledge in geography. Mike does not take this lightly, and sees it as Sulley teasing him for having one eye. But Sulley makes amends with Mike, and goes back to the canteen for some donuts. Mike briefly stays behind, but quickly changes his mind when a dog begins growling at him offscreen. Sulley promptly grabs Mike, and they return to Monsters. Inc. The background music is taken from the 1989 comedy Midnight Run, the theme of character Alonzo Moseley, who was played by actor Yaphet Kotto.
  • In a preview shown before the first Harry Potter film, Sulley is shown playing charades with Mike, but Mike is unable to guess the phrase "Harry Potter." The clip never specifically mentions Harry Potter, but the end states that Monsters, Inc. is playing right next door. Afterwards, Mike attempts to charade, but a bored Sulley quickly and correctly guesses Star Wars. A bewildered Mike asks how he does it.
