There have been a rash untitled Pixar films that have been announced over the last few years – The Untitled Film About Dinosaurs (now called The Good Dinosaur), The Untitled Dia de los Muertos Film, and The Untitled Film That Takes You Inside The Mind. From the little that we know about these three films, I have found the Mind film to be the most intriguing, mostly because it is to be directed by Pete Docter, who sat in the director’s chair for Monsters, Inc. and Up. We had been unsure of when the film would receive its title, but a report has just emerged that the Docter film will be called The Inside Out.
Bleeding Cool‘s Brendon Connelly reports that a source has told him that the long untitled Docter film would be officially titled The Inside Out soon. As further confirmation, he points to Primissima, to which Stefano Bethlen, the man in charge for Distribution for Disney in Italy, referred to a 2015 Pixar film and called it The Inside Out.
If the film is to receieve that title, it would certainly be in keeping with the relatively simplistic titles that we are used to seeing emerge from the Emeryville studio (Toy Story, Cars, Up, etc.). However, the report remains uncofirmed and will likely stay that way until Disney/Pixar makes the announcement. As Connelly notes, the title may yet be changed before it is announced. Stay tuned for more!
