During the early Nineties, the animation and visual effects industries transformed rapidly from their traditional old-school techniques to the use of computer generated imagery. One of the lost arts was "Dynamation", invented by the late, great Ray Harryhausen. Once considered the best and most revered method for integrating creatures into live action movies, Dynamation is now long obsolete. Although this Harryhausen-created procedure was generally considered to be a magician's secret, a few other masters such as Jim Danforth, David Allen, Randall William Cook, Jim Aupperle, Phil Tippett, and Doug Beswick all knew and practiced the art. The procedure involves animating a realistic stop-motion puppet in front of a rear-projection of live action footage. Foreground elements are masked out on a glass sheet in front of the camera and then restored by backwinding the film and running a second pass. The result is the illusion that the animated character is in the scene and interacting with the actors in the movie.
While employed by Full Moon Entertainment in 1994-1995, I was fortunate enough to have the opportunity to animate using the Dynamation technique on five separate movies. One of these productions, Magic Island, had the distinction of being the last feature film released which utilized Harryhausen's legacy process!
