Sleeping Beauty is a 1959 American animated musical fantasy film produced by Walt Disney based on The Sleeping Beauty by Charles Perrault. The 16th Disney animated feature film, it was released to theaters on January 29, 1959, by Buena Vista Distribution. This was the last Disney adaptation of a fairy tale for some years because of its initial mixed critical reception and underperformance at the box office; the studio did not return to the genre until 30 years later, after Walt Disney died in 1966, with the release of The Little Mermaid (1989). It features the voices of Mary Costa, Eleanor Audley, Verna Felton, Barbara Luddy, Barbara Jo Allen, Bill Shirley, Taylor Holmes, and Bill Thompson. The film was directed by Les Clark, Eric Larson, and Wolfgang Reitherman, under the supervision of Clyde Geronimi, with additional story work by Joe Rinaldi, Winston Hibler, Bill Peet, Ted Sears, Ralph Wright, and Milt Banta. The film's musical score and songs, featuring the work of the Graunke Symphony Orchestra under the direction of George Bruns, are arrangements or adaptations of numbers from the 1890 Sleeping Beauty ballet by Pyotr Ilyich Tchaikovsky. However, unlike the previous feature-films, this was the first Disney feature-film that did not have the same background animation material, but instead with new background animation material. Sleeping Beauty was the first animated film to be photographed in the Super Technirama 70 widescreen process, as well as the second full-length animated feature film to be filmed in anamorphic widescreen, following Disney's own Lady and the Tramp four years earlier. The film was presented in Super Technirama 70 and 6-channel stereophonic sound in first-run engagements.
