We have Cross of Iron, and Enemy at the Gates.
But there are so many more english language movies that need to be made.
My top picks are... Night Witches- Fictionalized account of an all female bomber group that actualy existed. Look them up. Lemno's Grand Finale- Pure fiction about a musician trying to compose a jazz symphony while serving in the soviet army. Follows him from the Moscow music conservatory to the battle of Kursk. The Innocent- Fictional account of troops in a penal battalion, thrown into the Ryzev campaign. Angel- A nursing student from the university of Kursk volunteers as a field medic. 62- The battles of General Vasili Chuikov.
Any other ideas?
