Asking if Germany has any WW2 movies is like asking if the US has ever made a movie about Vietnam. But then, Vietnam was ONE of many pivotal points in US history of merely 241 years, but WW2 and all of the surrounding events was THE event in German history, which reaches a bit more back in time. So much of post-war art in Germany, including cinema, dealt with the realization, shame, guilt, processing and the preventing of suppression of that monstrous events.
It immediately started in literature and arts, also some earlier film classics have been made, like the aforementioned “Die Brücke”, but in post war Germany up to the middle sixties, probably guilt-laden everday people preferred to get escapism out of the movies instead of confrontation with their ugly past, so mostly German cinema shunned this theme, with some very other notable exceptions like “Des Teufels General”.
As I said, German literature didn’t have much of these hang-ups, as it catered more to the more educated classes. With the student movement of the middle/late sixties, some of those dams broke, but I think it was the screening of the TV series “Holocaust” in Germany that really inspired many German filmmakers to tackle the time period. Since then many remarkable German movies about WW2 have been made which have already been mentioned here, like “Das Boot”, “Stalingrad”, “Der Untergang” etc.
Note that the ratio between movie and TV market in Germany tends MUCH more toward TV than in the US for different reasons, so additionally to the movie productions there have been made tons of TV movies, series and documentaries about the times.
The weakness in the US/Vietnam analogy is this: you won’t find a German “Rambo” or “Missing In Action” about WW2, but rather exclusively “Apocalypse Now” or “Platoon”. There won’t be much heroism shown in military actions, but rather in humanitarian acts. The typical hero of a German WW2 will be a kind and upright person, it can even be a Wehrmacht soldier, but not one of those who plows down 200 enemies with one machine gun. Far, VERY far from that.
(I really don’t know if those kinds of movies exist, at least none of big budget German productions. But coming back to the literature angle, there was an outlet for those fantasies, the "Landser pulp books)
