Can you believe Monsters Inc. hit UK screens 13 years ago this week?
That's right Sulley, Mike and Boo arrived in 2002, which means that 2-year-old Boo, would be 15 now. Crazy.
To celebrate the 13th anniversary of Monsters Inc. here are 13 things that you (probably) didn't know about the monsters of Monstropolis...
1. The initial idea for Monsters Inc. was for a grown man to be haunted by monsters he drew as a child.
Writer/director Pete Docter conecieved it as a 30-year-old getting haunted by the monsters he drew as a boy.
2. Pixar conceived the idea for the films Monsters Inc., Finding Nemo, A Bug’s Life, and Wall-E during one lunch meeting in 1994.
In the Summer of 1994, while working on Toy Story, key Pixar creatives, including John Lasseter, Andrew Stanton, Pete Docter and Joe Ranft, had lunch in a diner called Hidden City Cafe.
During this lunch meeting they ended up brainstorming the ideas that eventually became the films A Bug’s Life, Monsters Inc, Finding Nemo and WALL-E.
3. In early drafts, the character of Boo was written to be six to tewlve years old.
The writers decided to make Boo younger because it would make her more dependent on Sulley.
4. Bill Murray would have been given the role of Sulley if he'd answered the phone.
Bill Murray tested for the role, but 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".
5. 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.
6. Initially, Mike was supposed to have no arms
The plan was for Mike to use his legs as appendages, but that caused difficulties in animation, so they gave him arms.
7. Mary Gibbs, the voice of Boo, was so young that it proved difficult to get her to stand in the recording studio and act her lines.
Instead, the sound recorders followed her around with a microphone and cut Boo's lines together from the things she said while she played.
8. Animators had to individually animate 2,320,413 million hair strands on Sulley for each frame.
9. Each frame of Sulley (and his 2.3m hair strands) took 11-12 hours to render
Considering each hour of film is over 100,000 frames, that's an awfully long time.
10. Billy Crystal was originally offered the role of Buzz Lightyear in Toy Story, but he declined.
They offered Crystal a future role in a Pixar film that they would tailor to his talents.
Crystal told them to "do what's best for your movie and don't forget me when something good comes around."
11. When Boo is in the bathroom she “sings” to the tune of Beauty and the Beast.
12. When Randall is practicing camouflaging into backgrounds of walls, one of the images given to him is the wallpaper Andy had in his room.
13. Roz was voiced by Bob Peterson, who also did the voice of Dug in Up.
Peterson, the movie's story supervisor, provided the temporary voice of Roz during production.
The nasal, sing-song voice proved to be such a success that they kept it in the final film.
