Disney: FANTASIA
The film was presented in Fantasound, an early stereo system devised at the Disney Studio, which required theaters to be specially equipped. Because of the expense, the film originally opened in only 14 theaters. The stereo sound enhanced the effect of the movie and won special certificates at the 1941 Academy Awards® for Walt Disney, technicians William Garity and John N. A. Hawkins and RCA, and for Leopold Stokowski and his associates (for unique achievement in the creation of a new form of visualized music).
