On March 23, 2012, Keane left Walt Disney Animation Studios after 37 years there. In a letter to his coworkers, he said, “I owe so much to those great animators who mentored me – Eric Larson, Frank Thomas and Ollie Johnston – as well as to the many other wonderful people at Disney whom I have been fortunate to work with in the past nearly 38 years. I am convinced that animation really is the ultimate form of our time with endless new territories to explore. I can’t resist its siren call to step out and discover them.”
