My earliest memory of Robert Duvall is in the film, "To kill a Mocking bird".
I have always been very impressed with his performances, especially with his Western portrayals. "True Grit" and "Lonesome Dove", etc, (just to name a very few).
I just finished watching "Stalin" staring Robert Duvall.
As is typical to his acting skills... it was excellent! Much to my surprise!
I had avoided this film for years, only because I thought the casting was So off for the main caricature. I was very wrong!!!!
True, it is not related to a cowboy flick, but, it does address his acting skills
My best,
