There's also an Italian flick about the Eastern Front that is pretty darn good. Can't remember the title.
would that be "The Battle of Neretva" by any chance? it was pretty good, Italian movie made in Yugoslavia about partisans vs italians/germans.
Battle of Neretva is Yugoslav movie, and very good at that. It was shot during late sixties or early seventies when Yugo national board of movies or whatever that body was called wasn't cheap when it was about to make a high budget movie.
So when you see a house being blown up in Yugoslav war movies from 60s/70s you can be sure someone actually blew the real house up, not some poor 10$ studio replica or model. Aerial shots of battlefield, mass charges over a mile-wide front, you name it. Whatever it was, it wasn't cheap movie making or CGI trickery. One may disagree with the motives and ideology behind the movie, but I for one truely enjoy good old Yugo war spectacles of the 70s.
Also, foreign movie stars were used: Neretva features Yul Brynner as partisan miner/engineer (great role, he had to blow the bridge against wishes of civilian refugees, but on direct order from Tito), Hardy Krüger (one of the best SS officer roles captured on film), great Orson Welles in the hilariously outworldly role of Chetnik "senator" (whatever it means). He gets killed by even worse badass chetnik dude, in a scene reminding of classic westerns.
(Later movie Sutjeska had Richard Burton in the role of Tito, too solemn for my taste, but I guess Burton wanted to make an impression on Tito himself, who occassionally dropped on the set to see what goes on.)
Italian star Franco Nero played the relatively prominent (and tragic) role of ex-Italian officer turned partisan in Neretva, which may be the reason why you confused it for an Italian movie.
Neretva is well worth renting in your local DVD outlet if you can find it.
Now, since I jumped in, as for the bad movies.... U-571 is everyone's favorite. Pretty much anything with that guy Dudikoff or S. Seagal is hilariously trashy (even if it's borderline as "war movie"). Windtalkers sucked big time but every movie featuring that IJA cap with "curtain" at the back gets points for style in my book.
I loved Thin Red Line, watched it couple times and was never bored, so count me in "I don't understand why TRL sucks for some guys" club.
Many of the John Wayne movies suck, though they are obviously product of some other, bygone era, and should be viewed as such. (Some have oneliners usable as sigs too.)
Pearl Harbor was fun though, if you knew what to expect and had FF button ready.
German Stalingrad was disappointement for me, I expected so much more from the team that made legendary Das Boot, but it's still far from being "bad".
