Jack the Giant Killer is a 1962 American heroic fantasy adventure film starring Kerwin Mathews in a fairy tale story about a young man who defends a princess against a sorcerer's giants and demons. The film is loosely based on the traditional tale "Jack the Giant Killer" and features extensive use of stop-motion animation. It was directed by Nathan H. Juran and later reedited and rereleased as a musical by producer Edward Small because Columbia Pictures, which released The 7th Voyage of Sinbad, threatened to sue Small. The original print without the music was released 30 years later with no protest from Columbia Pictures, while United Artists continues to own the rights to the musical version of the film. The film reunited Mathews, Juran, Small and actor Torin Thatcher, all of whom had worked on The 7th Voyage of Sinbad.

Amid the chaos, the ship's captain is murdered, and Elaine is captured. Jack wants the ship to follow the kidnappers, but the
