Well, I was unable to find "Invincible" on NA You Tube, but did stumble upon "Indestructible", another Russian WWII movie. I'm not sure if I am currently watching it because there were no opening screen credits. It's 2hrs about Stalingrad and production quality is quite good. So, now I am just badly confused.
Looked at above trailer and the movie I am watching is not that one. I'll try to figure out what it is, but ti's late so...
