I saw this in the theater
I actually saw this in the theater in the late 70s when I was about 8 years old. It was an old drafty run down 1920s movie house. I remember even at that young age the atmosphere of the rundown theater helped to really make the viewing of this low budget docu-drama seem memorable.
I have a bootleg VHS tape, but it should be on DVD. I know Sunn Classic Pictures is in business. They have a website. All of those Sun Classic films should be released.
