The makers of Casablanca (1942) could not have known that the film would become a classic, since it is set during World War II. But all these years later, the story of a man (Rick) and a woman (Ilsa) who sacrifice their love to serve a higher purpose (defeating the Nazis) remains timeless.

Casablanca won three Academy Awards for Best Picture, Director and Screenplay and remains one of the most popular films of all time, ranked at the top of many film critics' lists. The film and its theme song, "As Time Goes By," have become pop culture icons.

The film is set in Casablanca, with most of the action taking place in a bar called Rick's, named after the hero of the story, played by Humphrey Bogart. The plot begins when an old flame, Ilsa Lund (played by Ingrid Bergman), suddenly shows up with her husband, Victor Laslow, who is wanted by the Nazis. Rick must decide whether to put his feelings for Ilsa aside and help Victor escape to help the resistance.
