In-Jokes

 * One of the stores in San Francisco is named "Krause", an allusion to supervising animator Shawn Krause.

Other trivia

 * This is the second Pixar movie to have a female protagonist. The first is Brave.
 * Like WALL•E before it, this film does not have a traditional villain. The closest it gets is Joy, who like AUTO in WALL•E, is just doing what she believes to be her job, oblivious to the harm she is causing. Unlike AUTO, Joy comes to realize her mistake and puts things right.
 * The film's teaser trailer features clips from all previous Pixar movies except Toy Story 2 and Cars 2.
 * Whereas in the original version the emotions of Riley's father are watching ice hockey during the dinner table scene, in most international versions, they are watching a soccer match. This can be seen when comparing the first US trailer with the corresponding UK trailer. A few international versions do retain the hockey match memory, like the Russian and French-Canadian ones.
 * Pete Docter has worked as an animator on another project which explored the brain (although on a less metaphysical and more physiological level): the Cranium Command attraction at Epcot.
 * Riley's hockey rink is located where the Walt Disney Family Museum is situated in San Francisco.
 * This movie took five years to complete.
 * The British comic The Beano made a reference to the film with "The Numskulls" having a story where Edd goes to watch Inside Out, only for Brainy to comment about it being similar to themselves, referencing the fact that some UK fans noticed some similarities between the two. The comic's editor-in-chief Mike Stirling explained: "We had people from all over the world pointing out the similarities, which is very flattering, but the Numskulls is a very British comic and we want to point out the differences." Ronnie del Carmen was also told about the comic during an interview with Den of Geek, which he said about the Numskulls: "I'm not familiar with it all."
 * The title does not appear until about 7 minutes into the movie. This marks the longest time the movie's title has taken to appear.
 * The puzzle box dinosaur world may be a reference to The Good Dinosaur.
 * The locksmith Krause has a notice in the window advertising: "Sure Locks for Homes," a reference to the fictional detective Sherlock Holmes.
 * Jordan's memory orbs are monochromatic (each has only one color) in both Inside Out and Riley's First Date?, implying that he's still emotionally immature.
 * Inside Out is the first PG rated Pixar film to have a non-human protagonist.
