Which Leo Tolstoy book was adapted into the 1956 film directed by King Vidor?

Leo Tolstoy’s book adapted into King Vidor’s 1956 film is War and Peace.

The American-Italian film stars Audrey Hepburn as Natasha Rostova, Henry Fonda as Pierre Bezukhov, and Mel Ferrer as Prince Andrei Bolkonsky. It adapts Tolstoy’s large historical novel about aristocratic Russian families during the Napoleonic Wars, particularly the French invasion of Russia in 1812.

King Vidor directed the film, which was released in 1956. The production was made in color and widescreen, reflecting the scale expected of a major historical epic. It received Academy Award nominations, including one for Hepburn as Best Actress.

Several other screen adaptations of War and Peace exist, including the influential 1966–1967 Soviet film directed by Sergei Bondarchuk. Naming the director and year is therefore important when identifying the 1956 version.
