When Leo McCarey made this film, America was only a number of months into WWII. The events leading up to the start of the war (at least in Europe) were known to some, with most of America still getting their news from the newsreels at the theater or radio. This film is a great way for people to learn about how the opening of WWII began, especially now where some schools are limited in their ability to cover the events. Two "average Americans" moving about Europe, sometimes steps ahead (or behind as in the Polish through Low Countries scenes) of the events which changed Europe. The time in the Polish Ghetto, as well as in Paris, allow for the audience to get to know the characters, without having to gather the facts as the story goes along. Just as National Treasure teaches about American History while entertaining, this movie belongs in the same group, as it tells a "You Are There" version of 1939-40 European History.
