Don Hahn's upcoming documentary, Waking Sleeping Beauty, is about the story of the so-called Disney "animation renaissance" that took place between 1984 and 1994. Many stars of the modern world of animation are featured in the documentary: John Lasseter, Jeffrey Katzenberg, John Musker, Glen Keane, Don Bluth, Roy Disney, Michael Eisner, and Tim Burton -- who appears briefly as a young animator miserably working on The Fox and the Hound.
You can see 11 video clips of the upcoming documentary at this link at CinemaBlend.com. (Burton is in the second clip for a few seconds at a rather amusing event.) No release date is announced yet, but it was most likely be released in theaters in 2010. The film is rated PG and is 86 minutes long.
Don Hahn, a producer at Disney, directed this documentary, and helped bring The Nightmare Before Christmas back to theaters in a new 3D presentation. Currently, he is an executive producer on the upcoming animated version of Frankenweenie.
