FBI Director J. Edgar Hoover and allies like Ayn Rand were convinced that Hollywood was infested with communists. Now they started scouring the movies themselves for evidence of propaganda. Anti-communist figures in the movie business, including John Wayne and Gary Cooper, create the Motion Picture Alliance for the Preservation of American Ideals to counter groups like the Writers Guild. Even American classics like It’s a Wonderful Life came under FBI scrutiny. Studios began to feel the pressure – even changing seemingly innocuous scripts to avoid political heat.
