From the Ray Harryhausen official website:
The Ray & Diana Harryhausen Foundation is pleased to announce the forthcoming release of the definitive Harryhausen documentary to be called RAY HARRYHAUSEN: SPECIAL EFFECTS TITAN which will be produced by Frenetic Arts, based in France, and the Foundation. This English language production is scheduled for completion in late 2011/early 2012.
Aside from interviews with the great man himself, shot over five years, there are also interviews and tributes from Vanessa Harryhausen, Tony Dalton, Randy Cook, Peter Jackson, Nick Park, Phil Tippet, Peter Lord, Terry Gilliam, Dennis Muren, Rick Baker, John Landis, Ken Ralston, Guillermo Del Toro, Jean-Pierre Jeunet, Robert Zemeckis, Steven Spielberg, George Lucas, James Cameron and many more.
For the first time Ray and the Foundation have provided unprecedented access to film all aspects of the collection including models, artwork and miniatures as well as Ray’s private study, where he designed most of his creations, and his workshop where he built them. In addition the documentary will use unseen footage of tests and experiments found during the clearance of the LA garage. Never before has so much visual material been used in any previous documentary about Ray.
