Natalie Kalmus wasn't just Herbert's wife—she was a force to be reckoned with in Hollywood. Known for her strict artistic control over the Technicolor process, she famously clashed with legendary filmmakers like Cecil B. DeMille, Michael Curtiz, David O. Selznick, and Michael Powell. Behind the scenes, her influence was valued and dreaded as she fiercely defended Technicolor’s vision. After her and Herbert’s relationship soured, she spent years in court, making his life a living hell and adding drama to an already colorful legacy.
