Casablanca (1942) is an American romance film directed by Michael Curtiz, starring Humphrey Bogart, Ingrid Bergman and Paul Henreid and featuring Claude Rains, Conrad Veidt, Sidney Greenstreet and Peter Lorre. It is set in the Vichy-controlled Moroccan city of Casablanca during World War II and focuses on a man's conflict between, in the words of one character, love and virtue: He must choose between his love for a woman and doing the right thing, helping her and her Resistance leader husband escape from Casablanca to continue his fight against the Nazis.

Although it was an A-list movie, with established stars and first-rate writers – Julius J. Epstein, Philip G. Epstein and Howard Koch received credit for the screenplay – no one involved with its production expected Casablanca to be anything out of the ordinary; Yet, despite a changing assortment of screenwriters frantically adapting an unstaged play and barely keeping ahead of production, and Bogart attempting his first romantic lead role, Casablanca won three Academy Awards, including Best Picture. Its characters, dialogue, and music have become iconic, and Casablanca has grown in popularity to the point that it now consistently ranks near the top of lists of the greatest films of all time.
