A classic 1942 film-noir movie starring Humphrey Bogart and Ingrid Bergmann.
Quick summary: Set during World War II, it focuses on an American expatriate who must choose between his love for a woman and helping her and her husband, a Czech Resistance leader, escape from the Vichy-controlled city of Casablanca, Morocco to continue his fight against the Nazis.
The movie had only 3 American-born actors (Humphrey Bogart, Dooley Wilson, Joy Paige). All the rest were international. Ingrid Bergmann being Swedish; Paul Henreid–Austrian; Claude Rains–British; Conrad Veidt–refugee German actor; Sidney Greenstreet–British; Peter Lorre–refugee from Austria-Hungary. Many others were from Russia, France, Germany, Canada, Denmark, et all.
A witness to the filming of the “duel of the anthems” sequence said he saw many of the actors crying and “realized that they were all real refugees”.Harmetz argues that they “brought to a dozen small roles in Casablanca an understanding and a desperation that could never have come from Central Casting”. They were frequently cast as Nazis in war films, even though many were Jewish.
