Favourite Fictional WWII Film Made After the War?

I am big into studying World War II, and I love watching movies based on its events. One thing I have noticed is that most WWII movies are basically biographical - it chronicles a real event, though it may have some historical inaccuracies for one reason or another. But I was thinking it would be interesting to compile a list where the mission(s) in the films are fake and the films are allegories, not biographical/documentary-esque.
