A soundtrack album of Bernard Herrmann's score was released on Colpix, Columbia's record label. In later years it would become one of the most sought-after albums by soundtrack collectors. It was finally released on CD, along with the full score, in 2009.
Initially, Ray Harryhausen wanted Miklós Rózsa or Max Steiner to score The 7th Voyage of Sinbad, but Charles H. Schneer persuaded Harryhausen to agree to hire Bernard Herrmann instead. Herrmann's score was so well received, and he worked so well with Schneer and Harryhausen, he ended up scoring three more of their films: The 3 Worlds of Gulliver, Mysterious Island, and Jason and the Argonauts. Harryhausen eventually got his wish, however, when Miklós Rózsa scored The Golden Voyage of Sinbad.
