There were Commie movies back in the day—but the propaganda was so subtle that modern audiences totally missed it.
The classic example was “Seconds” starring Rock Hudson.
The anti-corporation “message” was not in any dialog—it was only in symbolism throughout the movie.
These days the Commies just try to cram it down your throat.
I watched it again thirty years later and absolutely blanched at what I was seeing. Commie Agitprop 101.
