Pixar is maturing. Some of the studio's more recent films, such as WALL-E and Up, introduced some more adult themes, concepts and issues. The upcoming feature Brave also looks to be a little more grown-up than some previous Pixar installments. Considering this, it isn't so surprising that the production company is headlining its first "scary" film, tentatively titled Dia de los Muertos (which is a Mexican holiday celebrating the dead).
However, it is unlikely that the movie will be a straight horror. Lee Unkrich — co-director of Toy Story 2, Monsters, Inc. and Finding Nemo, and sole director of Toy Story 3 — is helming the new project, which will be based on an original story.
In other Pixar news, the company's long-untitled dinosaur film has gotten a title and a release date: The Good Dinosaur, coming out May 30, 2014. Additionally, the Monsters, Inc. prequel Monsters University is planned for June of 2013.
