In 1939, as the world perched on the brink of World War, "Sons of Liberty" served to remind the American public of the sacrifices necessary to preserve our freedoms, particularly freedom of religion. And its focus a Jewish patriot might be seen as an appeal to recognize the contributions of Jewish Americans during the American Revolution and to sympathize with Jews who were undergoing religious persecution in Germany and elsewhere.
One has to wonder how much of the story of "Sons of Liberty" is true. It feels like a fabrication with only the most basic facts being true. The use of the breathless voice-over, sounding like an episode of Zorro, only serves to heighten the feeling that "facts" were embellished and even created.
As a young student in the public school systems, I was familiar with the dramatized and sterilized versions of history--where the motives were so pure and the lines of conflict so clear. Such colorful but biased reconstructions of history only served as impediments in my later search for historical truth.
"Sons of Liberty" is so overly dramatized that its value as a revolutionary recounting is practically nil. It is understandable that Hollywood might produce such a piece in 1939 given the world situation. But now, its super-stylized, bombastic approach to story telling--with chronological events so condensed and orchestral flourishes for every scene--makes it only an interesting remnant of the run up to WWII.
