I might watch Kutusov sometime. I did find a Youtube channel with English subtitles. I wonder why they're all wearing their cocked hats pushed back. Seems odd. Maybe because it was a war, they had a problem with hat sizes.
I agree with reading history rather than watching movies and TV shows, because they always change things around, and you get an unrealistic version of what happened.
Reading, you are able to think and re-examine whatever you've studied, where film is all immediacy and emotion.
I've been reading David Irving's Churchill's War, and he's a fascinating historian, and although the books are 700 pages long, they're never boring.
He's also a good lecturer. I met him several years ago and bought a copy of Hitler's War.
