This 1997 film is based on the true story of the musical group The Comedian Harmonists, who were very popular in the years before WWII. As some of the members were Jewish, the war meant the group faced issues that risked their careers and even their safety.
Among my favorite war movies, Harmonists shows the humanity in the Germans of the time and the real concerns of publicly disagreeing with the opinions of the time. There is little action involved, which does set it apart from other war movies – it makes it more meaningful overall. It’s not about the special effects, but rather the music and the people who create it.
This film is rated R in the U.S. due to brief nudity, which could be edited out. The parental guide section in IMDB includes several typos, but is very detailed and worth looking at. This film is incredibly educational, in the realms of history and culture, and could lead into a musical lesson using their work and the many modern musical groups who include the Comedian Harmonists as their influences, such as Wise Guys and Max Raabe.
