All the Brothers Were Valiant is a 1953 Technicolor adventure drama film produced by Metro-Goldwyn-Mayer and directed by Richard Thorpe.

The film's screenplay was written by Harry Brown and based on the 1919 novel All the Brothers Were Valiant by Ben Ames Williams.

In 1857, Joel Shore (Robert Taylor) returns to New Bedford, Massachusetts, after three years at sea, and learns that his brother Mark (Stewart Granger), captain of the whaling vessel Nathan Ross, was reported missing from his ship months earlier.

Mark and his wife remain barricaded in the ship's cabin while the other two men, Quint (Kurt Kasznar) and Fetcher (James Whitmore), bide their time on deck.

Several weeks later, they stop at a small island to pick fruit, and Fetcher murders their two native divers, then tries to kill Mark.

Interpreting Joel's lack of resistance as a sign of cowardice, Priscilla is ashamed of her husband, and as Mark comforts her, they kiss.

Joel assembles the men and tells them they will not search for the pearls, proposing instead that he and Mark return to Tubuai and fight a duel.

The angry crew attacks and Mark --- determined not to have his brother's blood on his hands --- is forced to fight on Joel's side.

Following the success of Captains Courageous, the studio announced that it would produce the film, to star Robert Taylor and Spencer Tracy.

Although MGM intended the film as a follow-up to All the Brothers Were Valiant and planned to again cast Robert Taylor and Stewart Granger, the project did not come to fruition.
