When Flor and Glasha meet the armed partisan on the island in the bog, Flor picks up his rifle, and it's so covered in mud he can't even use it. Yet when they're led to his burned father, and he turns around after he speaks, the rifle is spotlessly clean.
When the villagers are about to be herded into barn( to be killed) the Russian 'colaborator' says in very clear English "Hauptmann do we invite them in,any signal or not.?"
The belted machine gun used by one of the Partisans to shoot the captured German soldiers does not eject any empty shell cases when it is fired.
The white stork that finds Flyora and Glasha in the forest is in reality a tame/captive and flightless bird: you can see that it has had all its secondaries and half its primaries cut off.
During 'the village scene' In the Russian/Byleorussian language version ,A Russian collaborator is clearly heard speaking in English to the German Commandant .This line is from the English dubbed version.
Many of the vehicles seen in this film are not the German standard Opel-Blitz truck nor the Kubelwagen car. Instead they are clearly post-World War II Soviet vehicles with slapped-on German Army markings.
The aircraft Flor and Glasha see flying over the forest seems to be a Focke-Wulf Fw 189 "Uhu", a close reconnaissance and light bomber plane. It had very little payload capacity and couldn't drop paratroopers.
In the barn scene near the end, a man peeks out the window and is immediately shot. In this moment, the audio of everyone else in the barn screaming stopped for a second and the gun sound effect played.
