I highly recommend the movie “Stalin” with Robert Duvall.
Oh yes— and... Robert Duvall was seriously psychotically scary—as Stalin. Am convinced he can play anyone appropriated to his stature, face structure etc. Brilliant actor whose first role... “Boo Radley” in To Kill a Mockingbird.
He is fantastic in “Gods and Generals” the sequel to Gettysburg, as General Robert E. Lee.
I mean- even the role as the guy running the shooting range in the Jack Reacher film (and later— as a combatant using an M1 Garand)===totally believable. “Open Range” another one.
And— Augustus McRae Texas Ranger in “Lonesome Dove”— no one else could have played him so well. Real empathy for his character (people still cry when he dies from the Indian arrow leg wound sepsis).
BTW— “Death of Stalin” is black humour at it’s best— Stalin not in it long-— the movie is excellent, and coldly funny about the sovietski system.
The other one really want to see is again a black comedy— “Red Monarch”-— David Suchet as Beria (a real life pervo- played very well) and forget who played Stalin.
Stalin was a monster. A Georgian priest candidate that instead became a che’ like person— loving death and murder and truly was a mass murderer.
