The Pixar Theory has been around since Pixar's earliest films and has been building and building an even stronger case for being confirmed as more films have been released. Long time Channel Frederator fans will know that we covered the Pixar Theory on the channel a few years ago, but we thought it was time to revisit it. With the release of Good Dinosaur, Inside Out and Finding Dory, the Pixar Theory has been updated so we had to cover it here. So how does it hold up?
