One was Clifford Odets, playwright, radical.. who named names himself later, according to sad accounts on Slate of "Kazan's victims."
They don't name the rest of the names in this article; they just say, "and several actors since forgotten, in part, perhaps, because they were blacklisted."
I've always been grateful that Marxists and Soviet spies landed on the blacklist and didn't have the Silver Screen on which to pour out their vitriol and hatred for America.
Think of the damage they might have done had they not been blacklisted!
