'The King's Captain') is a 1960 French–Italian swashbuckler film directed by André Hunebelle and starring Jean Marais, Bourvil, Elsa Martinelli and Lise Delamare.

The story unfolds in France in the early 17th century, with Louis XIII just coming of age while his mother, Marie de' Medici, continues to rule with her favorite, Concino Concini, who is the prime minister.

Among these nobles is François de Capestang, a brave knight determined to fight for justice and protect his king's crown, as well as the life of Gisèle d'Angoulême, whom he owes a debt of gratitude for saving him in battle.

Béatrice de Beaufort, initially aligned with Concini, switches sides after the death of her father, warning François and the conspirators of impending danger.

In a climactic battle at Saint-Leu castle, François and his allies face off against Concini's forces, ultimately emerging victorious with the timely arrival of King Louis XIII.
