Overview
The Magic Sword (also known as St. George and the Dragon, St. George and the Seven Curses, the film's original title, and The Seven Curses of Lodac) is a 1962 American adventure fantasy film directed by Bert I. Gordon that is loosely based on the medieval legend of Saint George and the Dragon.
Plot
George is the foster son of Sybil, an elderly, somewhat ineffectual sorceress. She brought him up after his "royal parents died of the plague" in his infancy.
He has fallen in love with the Princess Helene, but she is kidnapped by the wizard Lodac, who brazenly informs her father that he intends to feed her to his pet dragon in seven days, in revenge for the death of his sister. George wants to go on a quest to liberate his lady love, but Sybil believes he is too young as he is only 20.
She tries to distract the youth by showing him a magic sword; a steed; an invulnerable suit of armor; and six magically frozen knights that he will command when he turns 21. The impatient George tricks Sybil and locks her in a cellar. He then leaves with the magical implements in the revived company of knights.
