Next up is The Good Dinosaur (formerly known as the Untitled Pixar Dinosaur Project), which will be directed by Bob Peterson and Peter Sohn, and is set for release May 30, 2014. Take a look at the official synopsis.

"What if the cataclysmic asteroid that forever changed life on Earth actually missed the planet completely and giant dinosaurs never became extinct? This hilarious, heartfelt and original tale is directed by Bob Peterson (co-director/writer, Up, writer, Finding Nemo) and produced by John Walker (The Incredibles, The Iron Giant)."

Finally, we have the Untitled Pixar Project That Takes You Inside the Brain, which has been given a June 19, 2015 release date. Pete Docter is directing along with Ronnie del Carmen. Check out the official plot rundown.

"Pixar takes audiences on incredible journeys into extraordinary worlds: from the darkest depths of the ocean to the top of the tepui mountains in South America; from the fictional metropolis of Monstropolis to a futuristic fantasy of outer space. From director Pete Docter (Up, Monsters Inc.) and producer Jonas Rivera (Up), the inventive new film will take you to a place that everyone knows, but no one has ever seen: the world inside the human mind."
