I am now very curious to know which movie from the display gets the most rentals out of being featured as a Nazi movie. Please report back when the display goes down!
The Keep - Nazis face off against a particularly nasty vampire. The book is better, though.
Valkyrie - About the von Stauffenberg plot. Not a perfect movie, by any means, but I was more impressed with it than I thought I would be.
The Eagle Has Landed - Silly, fun movie about the Nazis trying to kidnap Churchill while he’s on holiday in an isolated English village. Yet again, the book is even better.
Saving Private Ryan - A great WWII movie, with some Nazis along the way, of course.
Fatherland - Not nearly as good as the book, but still an interesting alt-history about the Nazi regime in 1964.
Hellboy - Great supernatural-Nazi opening. Don’t mess with Kroenen, baby!
It Happened Here - A low-budget but interesting 1966 film about a hypothetical Nazi occupation and the British Resistance. Great footage of German troops marching past the Palace of Westminster.
Eye of the Needle - A Nazi spy races across the UK to tip off Hitler that the Allies won’t be landing at Cherbourg in June 1944. Chilling and clever.
*
Enemy at the Gates* and Stalingrad - A Russian and a German POV on that crucial battle. Both uneven but worth a look.
Notorious - One of my favorite Hitchcock movies. A great romance and an even better thriller.
Conspiracy - Pretty good HBO movie about the Wannsee Conference, with Kenneth Branagh as Heydrich and Stanley Tucci as Eichmann (despite neither looking much like his character).
As **delphica **notes, Top Secret is about Cold War East Germans, but they’re Nazis to all intents and purposes. My favorite scene: the officer who has a rubber stamp that prints, “Find them and kill them!” 
Somebody really should film Len Deighton’s SS-GB, another alt-hist classic about a murder mystery and conspiracy in German-occupied Britain. I re-read it every few years and enjoy it all over again.
Where? German soldiers does not equal Nazis.
One of my favorite serious WWII movies Come and See. Brutal and truly disturbing.
And my favorite slightly goofy WWII movie starring Frank Sinatra Von Ryan’s Express.
The guy who
stabs the Jewish soldier to death while whispering to him
was Waffen-SS, wasn’t he? It’s been awhile since I’ve seen it.
Yes, added Come and See this morning–DUH! a masterpiece.
Me, I hate Von Ryan’s. And it takes place in Italy. I remember the Fascisti, but I don’t specifically remember Nazis?
Come to think of it neither do I. It could quite possibly be 100% Nazi free.
In the book at least I believe the action takes place after the Italian surrender when the Germans took over thee camp. Until then the POWs had been having a comfortable relationship with the Italians. I definitely remember the description of the German guards on top of the carriages, wrapped in their capes, as madonnini, little madonnas.
Yes, from the movie I remember part of the plot hinged on a character (the chaplain?) being able to speak fluent German.
Of course, a German is not necessarily a Nazi.
The Train
The Boy in the Striped Pyjamas
The movie starts with the camp being run by the Italians under command of a cruel facist. The guards leave after the collapse of the Italian government. The prisoners are recaptured by the Germans. The prisoners are placed on the train to send them to Germany. The bad guys are all German. They don’t present their Nazi party credentials but I think it is safe to put them in this category.
Interesting fact I found out (book vs movie) when I was looking at wiki to make sure my memory was right.
One of the few times I have seen where the movies ending was changed from the book to make it an unhappy ending. In the movie Ryan dies trying to get back to the train. In the book he lives and escapes to Switzerland
Loach, you are absolutely right. The POWs were comfortable after the guards left.
Another change from the usual movie formula: In the book AFAICR, all the major roles were played by Americans, except for the British CO. In the movie Ryan (Sinatra) was the only American character.
Talking of escape to Switzerland, how about Hannibal Brooks ? Oliver Reed and an elephant!
Hart’s War
It was a tV show not a movie, but the Star Trek TOS episode “Patterns of Force” should be mentioned here, where Spock & Kirk go to Planet Nazi.
I am not sure if it is 100% NAZI-fied, but The Boys From Brazil. and I am not entirely sure that this would count as Serious NAZI stuff, but The Producers and their “Spriiiiiiing Time FURRRRRRR Hitler…In Gher…maaaany!” is one of meine…my favorites.
Schindler’s List
At IMDB I put in Nazi .
**Vague memory **of a cartoon about the concentration camps. Cats and Mice. Cats were Nazi’s and Mice were jews, iirc.
