"Waking Sleeping Beauty is no fairytale. It is a story of clashing egos, out of control budgets, escalating tensions… and one of the most extraordinary creative periods in animation history. Director Don Hahn and producer Peter Schneider, key players at Walt Disney Studios Feature Animation department during the mid1980s, offer a behind-the-magic glimpse of the turbulent times the Animation Studio was going through and the staggering output of hits that followed over the next ten years. Artists polarized between the hungry young innovators and the old guard who refused to relinquish control, mounting tensions due to a string of box office flops, and warring studio heads create the backdrop for this fascinating story told with a unique and candid perspective from those that were there. Through interviews, internal memos, home movies, and a cast of characters featuring Michael Eisner, Jeffrey Katzenberg, and Roy Disney, alongside an amazing array of talented artists that includes Don Bluth, John Lasseter, and Tim Burton, Waking Sleeping Beauty shines a light on Disney Animation’s darkest hours, greatest joys and its improbable renaissance."
