The film’s musical score and songs, featuring the work of the Berlin Symphony Orchestra, are inspired from the 1890 Sleeping Beauty ballet by Pyotr Ilyich Tchaikovsky.Sleeping Beauty was the first animated feature to be photographed in the Technirama widescreen process. The film was presented in Super Technirama 70 and 6-channel stereophonic sound in first-run engagements. Only one other animated film, Disney’s The Black Cauldron, was shot in Technirama.
