I don’t know if this is true? Or falsev or I don’t know ⬇️
Since everyone was scared of communism, Hollywood started making blacklists of people who weren't allowed to participate in movie making because it was feared that they would use the movies as a medium for spreading their ideological beliefs.
Blacklisting in Hollywood happened in the late 1930's but wasn't until 1947 that hearings were held to investigate Communism in Hollywood. Yes McCarthyism and blacklisting in Hollywood could happen again.
