 Rathbone earned Academy Award nominations for Best Actor in a Supporting Role for his performances as Tybalt in "Romeo and Juliet" (1936) and as King Louis XI in "If I Were King" (1938), a truly remarkable, comedic performance as the wily king.In "The Dawn Patrol" (1938), he played one of his few heroic roles in the 1930s, as a Royal Flying Corps (RFC) squadron commander brought to the brink of a nervous breakdown by the strain and guilt of sending his battle-weary pilots off to near-certain death in the skies of 1915 France.Errol Flynn, Rathbone's perennial foe, starred in the film as his successor when Rathbone's character was promoted.
