In the fifties, there was the blacklist, the Hollywood Ten. There was something that preceded it, that to my knowledge has never been written about, which was a group of communists or actors who they could persuade to become communists in their movies and there was a lot of bitterness on the part of right-wing actors that they were blacked out of a lot of these movies, and this preceded the left-wing blacklist that happened because there were these communist directors who were blacklisting not just right-wingers, but non-communists, and out this came rage on the part of the right, and they began to call anyone who didn't agree with them a communist.
