Hollywood had not been infected by the left yet.
Yep. In 1981, Hollywood was still plenty filled with holdovers from the 1940s, 50s, and 60s.
And America still had a moral core.
In 1946, then New Deal Democrat Ronald Reagan clashed with the communists who had secretly won control of the politically-minded Independent Citizens Committee of the Arts, Sciences and Professions. Reagan then attended a private meeting with a handful of actors and production people of similar views and experience in opposing communist influence in the group.
At that meeting, Reagan and old friend Olivia de Haviland humorously exchanged lines to the effect that "But I thought YOU were one of them!" (Communists). If Hollywood were a better place, we would have quite a movie about the professional and personal courage of such anticommunists, many of whom were prominent actors and producers.
