Haunted by his part in creating the racist Ham and Eggs at the Front (1927), Zanuck began tackling serious issues, breaking new ground by producing some of Hollywood's most important and controversial films. Long before it was fashionable to do so, Zanuck addressed issues such as racism (Pinky), anti-Semitism (Gentleman's Agreement), poverty (The Grapes of Wrath, Tobacco Road), unfair unionization and destruction of the environment (How Green Was My Valley), and institutionalized mistreatment of the mentally ill (The Snake Pit). After The Snake Pit (1949) was released, thirteen states changed their laws. For his contributions to the motion picture industry, Zanuck earned three Irving G. Thalberg Awards from the Academy of Motion Picture Arts and Sciences; after Zanuck's third win, the rules were changed to limit one Thalberg Award to one person. 20th Century Fox, the studio he co-founded and ran successfully for so many years, screens movies in its Darryl F. Zanuck Theater.
