Baker announced his retirement on May 28, 2015: "First of all, the CG stuff definitely took away the animatronics part of what I do. It's also starting to take away the makeup part. The time is right, I am 64 years old, and the Business is crazy right now. I like to do things right, and they wanted cheap and fast. That is not what I want to do, so I just decided it is basically time to get out. I would consider designing and consulting on something, but I don’t think I will have a huge working studio anymore."
