Soviet citizens in Moscow may have had more than one film to choose from because they had more than one state run theater to choose from. The vast majority of the Soviet citizens had access to one state run theater, and whatever they were showing was what they saw, period. Every film that was exhibited was considered propaganda, even cartoons.

I have seen a lot of Soviet cinema including all of Sergei Eisenstein's films, and some of it is really good, but it is still propaganda. The best later Soviet film is Andrei Rublev about the great Russian icon painter from the 15th Century. It was made in 1966, won prizes at the Cannes Film Festival, but it wasn't shown to the Soviet public until censors had butchered it in 1971. The director Tarkovsky defected from the USSR in 1985.

I don't think that you understand what a totalitarian state is.
