Inside Out is the 15th film to come from Pixar's computer animation studios and it focuses on what goes on in the mind of an 11-year-old girl.
The film is the first Pixar feature to use Dolby Vision which claims to offer a better quality of picture.
It's also one of the first animations to explore themes like why we sometimes feel happy, and why we sometimes feel sad.
We asked some kids who had just watched the film what they thought.
