I'm not sure if someone mentioned it already, but a good war movie that I saw recently was When Trumpets Fade. It was about the Jurtgen Forest Battle that cost 30,000 casualties on the side of the Allies. You don't here too much about this campaign because it's sandwiched between D-Day and The Battle of The Bulge. Others include:

Seargent York
Kelly's Heroes (hilarious)
A Bridge Too Far
Where Eagles Dare
Tobruk
Glory
Saving Private Ryan
All Quiet on the Eastern Front
Das Boot
The Iron Cross
Enemy at The Gates
Sands of Iwo Jima
Battle of The Bulge
Patton
