Walt Disney Studios veteran Don Hahn directs and produces this documentary that shines a light on Disney animation work during the 1970s, '80s and '90s -- from the team's humble beginnings at CalArts to the box office triumph of The Lion King. In exploring the works of that era, the film illuminates the careers of top animators of the time, including John Lasseter, Brad Bird, John Musker, Ron Clements and many others.
