Here are a few that have been missed.
"come and see" [russian] this for me is better than every war movie in existence,i've watched it about five times so far,and will probably watch again a few more times.
"Talvisota" also known as the winter war [finland] this is one of the best known Finnish movies,and is shown all the time in finland,again another very powerfull war movie.Its about the small finnish army facing the relentless assault from soviet forces during world war 2.
"Escape from sobibor" i only saw this recently,but it's many years old now,this for me was as powerfull to watch as schindlers list,there is some similarities in both films.
"Katyn" [polish] this is about the russian genocide during world war 2 of unarmed Polish soldiers.The germans got the blame initially for the genocide.
"Days of glory" [french] a recent film about muslim men fighting to the end on behalf of France in world war 2.
Quote "After seeing this film, French President Jacques Chirac agreed to restore veterans' pensions to the North Africans who fought alongside French troops during the war".
"Savior" about attrocities in bosnia, i don't know which country made this film,it's an oliver stone film,and the director is serbian.
Personally i'm not very keen on most of the war films made from 1950 to around 1970,the sort where american and britian rarely lose a soldier in battle,yet wipe out thousanRAB of opposing troops,these are too unrealistic for me.
