Striving to make the greatest animated film of all time, visionary animator Richard Williams (‘Who Framed Roger Rabbit’) toiled for more than a quarter century on his masterpiece - only to have it torn from his hands. Filmmaker Kevin Schreck has woven together mind-blowing animation, rare archival footage, and exclusive interviews with key animators and artists who worked with Williams on his ill-fated magnum opus to bring this legendary story to the screen. A tale of creative genius gone horribly awry, PERSISTENCE OF VISION is the untold story of the greatest animated film never made.
