Blooper

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.

When Aino explains what Sisu is, her hair is hanging into her face, but changes in between shots. Sometime a lock hangs right next her nose, sometimes it does not, but is at the side of her face.

The dog is not taken aboard the plane, impossible for Aatami to carry and the Nazis didn't grab it, they wanted it dead. But then after the plane crash, Aatami has the dog wit him in the motorcycle's sidecar..

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.

The C-47 plane was actually built under license in Russia during ww2 under the name Lisunov Li-2.

Real German military vehicles would not have civilian license plates mounted on them.

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.

The movie suspends realism, however there is no way the main character, or any of the Nazi soldiers could have carried and effortlessly tossed around that much gold. It would be the equivalent of carrying around an entire home gym set of dumbbells.

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.

On the other hand, Bruno appears to care more about his own well-being than that of his soldiers. He is most likely keeping the tank behind them to use them as a human shield rather then trying to protect them.

Ordinary German soldiers would not expect to be executed. Very few were, though some died as Soviet prisoners of war. They were also expecting better treatment if they could surrender to the Allies, which from Norway would have been virtually certain.

This may, however, not have been widely known among the soldiers during the war. They may also have been told differently by their commanders to make them easier to lead.

When the gold-miner finds his way inside the German plane, a large Hammer and Sickle emblem is shown on the bomb, which is a symbol of the Russian army.

This emblem officially represented the Soviet Union, and it would be considered historically inaccurate for a Nazi Germany plane to have this displayed on its bomb.

However, this is not the film makers being ignorant of the symbols of the Soviet Union and Nazi Germany. It is likely that the Nazis has painted the enemy symbol on the bomb as a cruel joke. (The pilot is Russian, it is a Russian plane, hence the Hammer and Sickle.)

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 T-55, which was not in service until 1948.

When the navigator in the tank checks the map to see where the plane will be waiting for them, he is holding a map of Slovakia, specifically Velky Slavkov near Poprad in northwestern Slovakia. This is almost 2000km away from Rovaniemi, where everything is supposed to happen, as at the beginning of the film the signpost shows that Rovaniemi is only 5km away.

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.
