Review of Hollywood on Trial

I saw this on TCM and it was introduced by Ben Mankiewicz who called this the "darkest period" in American history. The House Un-American Activities Committee investigated Hollywood for communist influences and the result was the infamous "Hollywood Ten". The Hollywood Ten were communist sympathizers--some were former sympathizers, others still believed in the cause. They were correctly blacklisted for years. These were not innocent men who were being crucified for mere political beliefs. Communism is antithetical to the American way of life. So these Hollywood Ten slimeballs believed in an idea to subvert the American way of life, then tried to hide behind the Constitution. That sounds pretty hypocritical to me. They were not and never will be heroes, despite how Hollywood tries to make them out to be saintly victims.
