I guess most people have heard of the 'anti-communist' theories behind 'Invasion Of The Bodysntachers'.
But what, in your view, is the 50s sci-fi or monster movie that is the most virulently anti-commie?
Were any film-makers in the genre well known for their politics?
I'd say (the very enjoyable) 'The 27th Day' is pretty un-subtley anti-Soviet. Are there many more?
