The film was five years in development and 14 months in production, and cost
$20 million. It failed to recoup its terrific cost, but wowed audiences
with the dazzling special effects created by A.C.E.S. (Automatic Camera
Effects Systems). All the sound stages at the Disney Studio were occupied
by the production. Nearly 14 months of simultaneous and post-production
filming and processing were required by the studio's photographic process
laboratory and special effects departments. In some scenes, as many as
12 different photo processes were used simultaneously on the screen. Four
Academy Award® winners supervised the special effects: Peter Ellenshaw,
production designer and director of special effects; Eustace Lycett and
Art Cruickshank, special photographic effects; and Danny Lee, special
visual effects. The film was nominated for Academy Awards® for Cinematography
(Frank Phillips) and Visual Effects. The film's original producer, Winston
Hibler, died during production. |
