Another pretty good movie in the "subtitles" category is "Fires on the Plain",made in Japan 1959. The movie takes place in February 1945 on the Phillapine Islands, and revolves around several rag-tag Jap soldiers who are facing either starvation, suicide, or.......... 
The title is your hint. I had to turn the sound off completely and just read the subtitles. After a while the sound of angry Japanese voices got on my nerves, but this was an important movie, for it was one of the first so-called "anti-war" movies made in post-war Japan, a country that was being run by it's military until the war ended. Worth renting.

Hmmm, yet another one I haven't heard of. I shall continue to rely on you for more.
A plethora of movie knowledge! You astound me! 
I finally got an opportunity to watch a film I've heard rave reviews about since the 1960's. Back then I wouldn't even consider watching a movie with English subtitles. The film I am speaking of is "The Seven Samurai" (1954), directed by Akira Kurosawa. Billed as an "heroic tale of honor and duty", this film was later adapted by Hollywood for western audiences as the classic American western "The Magnificent Seven," which has been a favorite of mine since I was a kid. I'll keep it short and say if you liked the remake you will also enjoy the original Japanese film...perhaps even more than you expected to! A wonderful story!

ps- I rented it from Netflix PSS- I know it's not WWII, but it is about courage,honor and duty so I didn't think you'd mind this infraction
Anyone seen "Die Brücke" (The Bridge) ?
It's about some young Germans deciding to defend an insignificant bridge (they even stop German engineers from blowing it as the Americans are closing in).
A fine movie and quite realistic.
It's in black and white.
Only the "Shermans" are a little bit comical to see.

No, I have not seen that one. That is something I would definitely remember. Must add the one to the long, long list of films to see.
Don't forget the three movies about the "7th Company".
These are French movies with Michel Galabru starring.
Original titles:
"On a rétrouvé la septième Compagnie."
"Mais ou est donc passé la Septième Compagnie?"
"La septième Compagnie au clair de lune."
It is about French soldiers in 1940.
Very hilarious at times, especially that French officer trying to blow up a bridge and not succeeding as he can't remember what color of wire to attach to the detonator.

I have "Die Bruke" and would say that it's one of the best films to come out of post-war Germany, and based on a true story.
Dogdaddy
You're right, Dogdaddy.
Another good one is "Das Boot" with Jürgen Prochnow.
The original version (where Germans speak German) is great eventhough it is about U-Boats.
It's very well made, the claustrofobic mood when they dive and the very sad ending mark this as one of the best ever seen.

Le fil vert sur le bouton rouge 
those french movies were very funny, do you remember the scene in the castle "trop chaud & trop froid " when they were hidding the others behind their mattresses
And that scene with the French shopkeeper who favored German troops not knowing it was them in German uniforms.
"Dit 'eil 'itleir!" (= Say Hail Hitler!)
Then they backed up the German halftrack and drove straight into that man's shop. 
Very good movies.
