Sergeant York (1941)
This has to be one of the earliest films on our list. Sergeant York came out in 1941 and shows the life of a World War I soldier called Alvin York. He killed 25 German soldiers and captured 132 more, making him one of the most decorated soldiers of the conflict. What helped the film stay true to the story was that York was an advisor on the set. The project showcased the realities of war and became the highest-grossing film of the year. The movie also helped boost American morale as the country just joined the Second World War around the same time.
Das Boot (1981)
We have another German film that did not shy away from depicting the horrors of war. The story takes place in 1942 and looks at German U-Boat crews during the Battle for the Atlantic. People appreciated its nuanced view of life inside a submarine and showed the struggles of German soldiers to understand what the Nazi party was doing. Considered one of the best films about U-Boat servicemen, Das Boot was able to show us a dim yet realistic portrayal of the people who lived through the war.
