The news slipped out in a Variety profile of up-and-coming screenwriter Derek Connolly, who revealed he is writing the project, and went on to share his thoughts on working at Pixar.
"It's totally different, the way they do things up here. You're here everyday. You don't go away for three months and come up with a script. You're involved with a director and it's very collaborative."
He adds that he was advised "not to dumb it down or treat animation like it's for kids".
