Alexandre Dumas's classic tale gets a slapstick musical twist as the daring D'Artagnan (Don Ameche) joins the famed heroic trio -- portrayed by the Ritz Brothers -- in their quest to protect King Louis XIII (Joseph Schildkraut) from the scheming Cardinal Richelieu (Miles Mander). Binnie Barnes and Gloria Stuart co-star in director Allan Dwan's rollicking adventure. Songs include "Chicken Soup," "My Lady" and "Voila."
