In spite of the various methods used by blacklisted personnel from Hollywood, many had their careers ruined by the link to Communist activities. Where writers could used false names and fronts, actors couldn’t hide because of their obvious visibility. Larry Parks, Karen Morley, Sam Jaffe and many other fine actors lost parts because of HUAC activity against them.
Eventually, because of changes in attitude and politics, the barriers were dropped along with the HUAC which was abolished in 1975 when its duties were taken over by the House Judiciary Committee. Like the fear of movie censorship in the early 1930's which brought about the Breen Production Code Administration (Hays Code) and the powerful Catholic Legion of Decency, the power of the HUAC had run its course and became just another interesting part of American history.
