And here is another Russian war movie I have not heard about before. When it comes to WWII, Russian cinematography will not let itself be outdone by Hollywood.
From watching the trailer authenticity seems to be good, with Panzers IV and III looking particularly well depicted, I also like the gritty atmosphere of the trenches, I don’t think it will get into distribution around here, so will have to look for it.
