At the dawn of sound, he wrote the story for the Academy Award-winning musical The Broadway Melody and collaborated memorably with Gloria Swanson and Joseph Kennedy for The Trespasser. He excelled at anti-war drama (White Banners, The Dawn Patrol, We Are Not Alone), fantastic Bette Davis weepies (Dark Victory, The Old Maid, The Great Lie), lilting romantic dramas (The Constant Nymph, Claudia), big-budgeted literary adaptations (The Razor's Edge), and even film noir (Nightmare Alley).
