Metamorphoses(星のオルフェウスHoshi no Orufeusu, "Orpheus of the Stars") is a Japanese animated film, originally released by Sanrio in the United States on May 3, 1979. The film is a retelling of stories from Metamorphoses by the Roman poet Ovid, set to rock music by Arthur Simms and Pattie Brooks. In all of its five parts, the protagonists are portrayed in the form of a recurring boy and girl. The movie was Sanrio's second animated release in the US (following their adaptation of The Mouse and His Child the previous year). Over 170 animators, all employed in Hollywood, worked on it for three years.
