What global events had just taken place and were taking place at the time of the film’s production?

Casablanca is an exploration of the universal themes of love and sacrifice, but when the film was released in 1942, audiences viewed it as a political allegory about World War II. The film is set in December 1941, the month in which the Japanese attacked Pearl Harbor.

Explain how these events may have impacted on the style and content of the film itself.

There was alot of realism in the film as it was filmed and set during World War II, it focuses on an American expatriate (Bogart) who must choose between his love for a woman (Bergman) and helping her husband (Henreid), a Czechoslovak resistance leader, escape from the Vichy-controlled city of Casablanca to continue his fight against the Germans.
