Casablanca: How An Unproduced Play Marched into Movie History

Warner Bros. adapted the unproduced 1940 play "Everybody Comes to Rick's" into Casablanca after the Pearl Harbor attack, capitalizing on American entry into World War II and wartime demand for patriotic entertainment. The 1942 film, starring Humphrey Bogart and Ingrid Bergman, premiered in New York just as U.S. forces entered the real Casablanca in Morocco, becoming an Oscar-winning classic whose famous quotes remain iconic in popular culture today.
