On Charlie Rose last month, Pixar head John Lasseter talked about Pixar's upcoming movies - including the Monsters, Inc. prequel we already knew about, and the untitled "Pixar's take on dinosaurs" movie we're eagerly awaiting. But then he added that the studio has a movie in development that takes place entirely inside a girl's head, with different characters portraying her emotions. This actually sounds truly creative, and we're left wondering — along with Ian Park at Beautiful Brain — whether this will be Pixar's take on neuroscience. Maybe Robert Downey, Jr. can play the voice of the nucleus accumbens!
