Have you ever heard of or seen A113 in a Pixar or other animated film? That is a reference to room A113 at CalArts, a classroom that all character animation students will spend time in during their studies. A113 has shown up in every Pixar film and many other animation films and TV shows, and even some live action films like Mission: Impossible - Ghost Protocol, which was directed by Brad Bird.
To see more proof of the influence of CalArts alumni on animation, take a look at this Cartoon Brew article that list most Disney, Pixar and DreamWorks films for the past 13 years with their directors and the director's school. Do you notice any recurring theme?
Below is a fun video of Austin Madison talking about his experience as a Pixar intern while attending CalArts. Madison is now a full-time animator for Pixar and just recently finished working on Brave.
