The folks over at AWN had the opportunity to interview Peter Sohn, director of the new Pixar short film, “Partly Cloudy.” The short will play before Pixar’s upcoming feature “Up,” in theaters May 29. Peter Sohn was previously an animator/story artist on various Pixar films, including Ratatouille, The Incredibles and Finding Nemo.

AWN: Talk about the pitch and how it went from there.

Peter Sohn: The original pitch was just as I explained: There’s the world of storks that deliver babies, but where do they get these babies from? And my answer was obviously the clouds. And I had done some drawings of these cloud characters — taking some photos and Photoshopping eyes and a nose in and then having some birds all flocking up to the skies. I pitched this story of a smaller gray cloud that [lived below and] made some of the dangerous babies. And I showed John these images and he touched on one of them and said let’s start developing this one. And that was close to a year-and-a-half ago and it’s been a really interesting learning experience for me. Obviously, this is my first [short]. It really is like raising a baby. I felt very much like Gus during this thing — making something and wanting people to like it.
