It is simple.
The USSR planted people not only in the movie industry but also primarily into the news media ownership and control.
Their “plants” were also to infiltrate the labor unions (PRIMARILY) the Teachers Unions.
Know your history even if the media won’t report it for you.
The USSR was not in existence till just before we entered WWI, and they were pretty busy with the White Red Civil War. Besides, they were at peace with Germany.

Is this a joke? The Tsar of Russia fell to revolution in 1916.
I’m confused by your post. Sorry.
