Motion Picture Score by Hans Zimmer and John Powell (score from The Road to El Dorado; for the soundtrack, they have to put all of the score for the movie)
Additional Score list by Michael Giacchino (Inside Out 1):
Nomanisone Island/ National Movers (for Inside Out 2, it's called Modern Life/ Heading to Camp Ramapo)
Tis might be distributed by 20th Century Fox (Relativity Media), and Walt Disney Studios Motion Pictures, and production by a new animation studio called Cartoon Network Pictures, and also animation by Pixar Animation Studios (as it is common for Inside Out 1).

Runtime Length: 101 minutes (1 hour 41 minutes 22 seconds)
Scene Selections: 24 (just a thought when they make the DVD/ Blu-Ray/ Digital HD versions of the movie; for the regular Aspect Ratio version 1.85:1) and 15 scenes for the Action-Adventure Awesomeness Version (2.39:1 aspect ratio to increase the extra awesomeness for the Action adventure scenes).
Hopefully, this will be a real sequel/ prequel (It takes place in my mind; DreamworksCompletist's mind).
Before the movie, in theaters, there (maybe) will be an animated prequel short film called Co-Brain's Guid to Living the Awesome Life, shown before the movie (supposedly) in theaters when it gets confirmed. All of the animators from The Road to El Dorado, are coming back to do the animation for Inside Out 2 as Tulio, Miguel, Chel, Tzekel-Kan, the Stone Jaguar, Chief Tannibok, Altivo and Bibo the armadillo.
