- The national anthem played by the Soviet Army at the commendation meeting was "Unbreakable Alliance", which had not yet been born at the time of the Battle of Stalingrad. It was first adopted in 1944, a year after the battle.
- Not long after the beginning, in the 1942 fascist power expansion picture that appeared, Switzerland was a neutral country at the time and was not invaded.
- During the Defence of Stalingrad, one regiment of the 13th Guards Division did not receive a weapon when it crossed the river. But the regiment’s weapons were adequately replenished that night. According to the video, the Soviet army was indeed one person with a Mosin Nagan rifle at the time, but since Vasily's unit was a recruit, it is possible that he could not get enough weapons. The authenticity of this shot needs to be verified.
- The Soviet army rushed through the German defense line, and then was beaten back by its own army to retreat. The same Soviet army died twice, the first time during the attack and during the retreat. When the Germans opened fire, the submachine gunner behind raised his gun three times in a row, using repeated shots taken from different angles.
- When Zesov accompanied Danilov to meet with Soviet officers, his sideburns were bleeding. In the next shot, Zesov's wound has been bandaged.
- Vasily should be a Siberian soldier. At that time, the Siberian soldiers had already put on winter clothes instead of ordinary military uniforms.
- Regarding Khrushchev’s inspection of Stalingrad and preventing citizens from fleeing the city, in fact the Soviet Volga Fleet transported some elderly people, children, and women across the Volga River and evacuated safely to the rear.
- It can be seen from some special angles that Danilov’s spectacle lenses have a reflective coating that is unique to modern spectacles.
- Regarding the confrontation between Vasily and Connie in the department store, the low-altitude bombing by German fighters in the nearby area became the best test for Vasily and his companions, but the bomb could not explode so close to the ground, especially It's over the city, so the explosion is likely to damage the aircraft.
- The bullets fired in the film always run too fast, and it takes a certain amount of time from pulling the trigger to hit the target with a considerable distance.
- Tanya's finger nails were smooth and shiny. Although it was 1942 and nail polish was invented by Michel Menard in the first half of 1920, it is still unlikely to be used by a Soviet soldier in the Battle of Stalingrad.
- In the opening battle scene, a soldier ran into a huge metal statue, but the statue moved.
- At the beginning, the Soviet army drove a line in the rear, but the rolling stock belonged to the German railway.
Enemy at the Gates behind the scenes gags

Vassili Zaitsev: On this day, September 20th 1942, a young shepherd boy from the Urals arrived in the city of Stalingrad on the banks of the Volga. His name is Vassilij Zaitzev. Like thousands before him he came to answer comrade Stalin's call. Armed only with a rifle, he quickly made the fascist invader realise that from now on he would be punished for every step he took in the motherland, that from here on the only way was back.

Vassili Zaitsev: Shouldn't we try and make the point that I'm not the only one fighting?
Commisar Danilov: That's an excellent idea. We can take it even further though. Your battle for the production of coal is as worthy as mine. There's no 'k' in coal. Just one 'l'. Tell me if I'm going too fast.
Vassili Zaitsev: No, you're not going too fast. Is there any other improvements?
Mother Filipov: Why don't you get some rest? These letters can wait until tomorrow.
Vassili Zaitsev: We should carry on. We're not tired. Thank you, Mrs. Filipov. These people took the trouble to write to us. Tomorrow we might not be around to write back.
