People posting on Twitter have independently verified our original story. Glen Keane has left Disney’s Feature Animation studio. He worked at Disney for approximately 37 years. Disney artists received an email late-Friday afternoon LA time with the text: “Glen Keane has decided that the time has come to take the next step in his personal exploration of the art of animation.” (UPDATE: Cartoon Brew has the exclusive full text of Glen Keane’s letter to his co-workers.) Keane had worked at Disney since 1974, though he left the studio in 1986 and worked as a freelancer for a period of time. If you have more info, please contact me.
