During the first fight scene, the soldier holding a gun to Aatami has windswept, messy hair. When he gets knifed in the head, his hair is tidy and groomed.
When Bruno is inspecting the downed aircraft, the top rope on his hat alternates above and below the skull emblem several times between scenes.
At one point near the end, the freed female captives are driving a truck in front of the tank. Aatami then jumps from the truck to the tank, and a fistfight between him and the SS, Wolf, ensues on top. Eventually Wolf and Aatami fall off the tank. Aatami wins the fight and leaves Wolf behind. The females who were driving the truck that was last seen in front of the tank appear inexplicably behind Wolf.
The anti-tank mines are triggered in turn by the horse, a rock, and humans. The most often used German T-Mi 35 antitank mine was triggered by a load of 440 lbs (190 kg) in the center, or 220 lbs (100 kg) on the edge of the pressure cover.
When the nazis hang Aatami he is hoisted up by Wolf. It is impossible to hoist something of roughly the same weight, using only manpower, without pulling yourself up instead.
The fighter plane used in the film was a Russian made Ilyushin II-2 not a German plane.
The second plane used was a C47 American plane which was a troop transport plane not a bomber.
Real German Military Vehicles would not have civilian license plates mounted on them.
The C-47 plane was actually built under license in Russia during ww2 under the name Lisunov Li-2.
Throughout the movie the tank is at or near the rear of the German convoy. This is irregular and not good practice in military, as the purpose of a tank in a convoy is to be at the front in order to better protect the convoy with its thick armor.
While Aatami is riding his horse you can clearly see the horse is wearing horse shoes. After the horse is blown up there is a closeup shot of the hooves of the horse and there are no horse shoes on either hoof.
The two Germans who go under the water to search for the go do not remove their helmets, which would have made it difficult to go deeper.
The Germans decide to hang Aatami by hoisting him upwards with the rope, instead of dropping him from a height while hanged. Had they dropped him like nearly everyone else does, the noose would have caught Aatami and broken his neck. Even still, the Nazis fail to ensure Aatami's dead, despite being well aware of the threat he poses.
While hanged, Aatami uses a loose screw in the wooden pole he's next to hook onto his open wound in order to gain height and relieve tension on his neck, but the screw was large enough and not deep into the wound enough and so should have simply tore Aatami's flesh.
The tank used by the SS platoon is a Soviet-made T-54/55 which was introduced well after World War 2, not even a T-34 which actually was available in 1945.
The German tank is actually a Russian T55 which was not developed until 1948.
Through the whole movie Aatami visibly wears 3 different knives in sheaths (puukko), but uses in fight only one of them, and only once.
Even in the hand-to-hand combat scene at the end of the movie, while being punched and kicked, he does not reach for the knife handle immediately on his own chest.
