American political parties have not been the only folks to visit Beverly Hills - hat-in-hand; Soviet-backed Reds have done it, too. This 1940 article goes into some detail explaining all the various false fronts that American Communists would erect in order to attract Hollywood's empathetic pretty boys - a tribe that is so easily separated from their wealth. Once an actor was hooked, they were steadily relied upon by the Reds to cough-up the do-re-mi without question; if they didn't - they got the works.
"Walter Winchell has already passed on to Washington documentary evidence proving that thousands of dollars contributed by Hollywood to innocent-sounding organizations eventually wound up in the hands of Communist leaders. Police and other investigatory groups have gone about accumulating evidence of the conspiracy."
One of the many Communist-front advocacy groups that milked Hollywood of much of its wealth was called the"Independent Citizen's Committee of the Arts, Sciences and Professions"; actress Olivia de Havilland was one of their willing dupes until she worked with the FBI and helped to bring them down.
