The new trailer for Inside Out 2 confirms the Pixar shared universe theory. The sequel, set to release on June 14, features some new emotion, Anxiety, Boredom, Envy and Embarrassment alongside the previously introduced emotions of Joy, Sadness, Anger, Fear, and Disgust. Fans eagerly await the release of the Pixar film.

Inside Out premiered in 2015 and followed a young Riley as she was uprooted by her parents from the Midwest to San Francisco. Following the move, Riley’s emotions — Joy, Fear, Anger, Disgust and Sadness — “conflict on how best to navigate a new city, house, and school,” per the synopsis.

Inside Out 2 confirms the Pixar shared universe theory

Inside Out 2's trailer features an easter egg, confirming the Pixar shared universe theory. This theory, created by Jon Negroni and popularized by the Super Carlin Brothers, states that every Pixar film takes place in the same universe and that elements from each film influence the others.

Inside Out 2's new trailer is the first time that one of the films acknowledges the fact that the different titles are all in the same universe, and it does so by subtly revealing a poster on the wall.

In the trailer, Riley is in her bedroom. Behind her, a poster of a band called 4*Town is hung on the wall. This band was present in Pixar's recent Turning Red movie, which means that Riley's having a poster of them on her wall definitively places Inside Out and Turning Red in the same universe.

Turning Red is set in 2002, and the first Inside Out is set in 2007, so the latter's sequel likely takes place a few years later. So, although Turning Red and Inside Out 2 are likely roughly around eight years apart, it still seems as though the 4*Town band is still together. More importantly, it confirms and continues the Pixar shared universe theory.


The original Inside Out movie shares similarities with Jon Negroni's Pixar Theory, with a rat in Inside Out resembling Remy from Ratatoullie and Carl and Ellie's wedding from Up can be seen in a memory. Negroni also suggested Riley's imaginary friend, Bing Bong, was a monster from Monsters Inc. who began as her personal monster.

Negroni revealed that this would explain why Bing Bong has animal-like features from cats, elephants, and dolphins because the monsters in Monsters Inc. have animal characteristics themselves.

The Super Carlin Brothers explained in a YouTube video how Turning Red connects to the wider Pixar shared universe. In that video, Jonathan "J" Carlin dives into how the witch from Brave is Boo from Monsters Inc., who is also the mother of Meilin's friend, Abby, in Turning Red.

In Brave, there is a carving of Sully in the witch's hut, and she has dozens of wooden bears that she has carved out because she always remembers Sully.


J Carlin described that Boo could have learned a lot about bear magic from Meilin's family in Turning Red and also could have learned about time travel from the Lightyear movie, which she would have been able to use infinitely to make sure that Sully is never forgotten.

Since the witch can turn people into bears in Brave, this theory also suggests that Boo could have traveled back in time to utilize that magic in the past as well.
