I just watched the movie again this time with Josh Cooley as a special guest. Josh Cooley was the head of the story board and also helped write the story. His next job is as director for Toy story 4. After the movie Josh did a Q&A so here are some cool facts about the movie.
There are a total of 127000 story board drawings in the final version of the movie, that is an averege of around 23 drawings per second of film
When comming up with the what emotions to use they consulted the leading brain scientists, some scientists said a person has only 3 emotions, another said 7 and one person said 28. Pixar decided to on five emotions because it worked best with their story.
One version of the movie had 28 different emotions, and that got really complicated very quickly.
The story is largely based of the director’s own childhood, at age seven his family moved from minnesota to Normway.
Pixar had to write new software to make the emotions who are actually created of particles. watching the movie you can see that the emotions look sort of furry, this is because they are made of moving particles.
