The film was released in the United States on August 7, 1987 after the popularity of the toy line and cartoon had peaked. On the Planet Eternia, at the center of the Universe, the forces of Skeletor (Frank Langella) have managed to seize control of Castle Grayskull and capture the Sorceress of Grayskull (Christina Pickles). Skeletor is planning to exploit Grayskull's hidden powers when the "Great Eye of the Galaxy", a portal in the castle's throne room, opens and Eternia's moon is correctly aligned with it. The remaining Eternian forces are scattered and outnumbered. One of Skeletor's patrols is attacked by Eternia's greatest warrior and Skeletor's archenemy, He-Man (Dolph Lundgren), veteran soldier Man-At-Arms (Jon Cypher) and his daughter Teela (Chelsea Field).
