It’s just such great storytelling. You go in, you fall asleep, you’ve experienced this whole thing and you come up and you wake up out of it and you’re just ‘What just happened?’ It’s magic.”Docter is now chief creative officer of Pixar Animation Studios and one of the forces behind Toy Story (1995), Monsters, Inc (2001) and Inside Out (2015). Monsters, Inc is getting the park treatment at Disney’s Hollywood Studios in Florida.
