Documentary On The Origin of Disney ImagineeringBy Norman Chan "During a gathering of Disney fans at D23 Expo on August 10, Walt Disney Parks and Resorts Chairman Tom Staggs premiered a trailer from an upcoming movie that explores the past, present and future of Walt Disney Imagineering by noted documentary filmmaker Leslie Iwerks." Iwerks, the granddaughter of Disney legend Don Iwerks, also directed The Pixar Story documentary in 2007. The only downside to this amazing preview footage is that the documentary is slated for release in 2016.
