Heal Hitler!(1986)

Stalingrad, 1942: just as he is complaining about the "blockheads" who are in control, a German named Herbert gets hit. Fast forward forty years after the war to Munich's Hofgarten, where in front of the patched-up ruins of the Army Museum, Herbert reappears, mistakenly believing he is still in Stalingrad, which the victorious Germans have destroyed and rebuilt in the image of Munich.
