Sad story of war

I read the book and watched the dvd.
A book without adaptation can be transplanted and I see that it was well done and respected the novel except the end.
This has profoundly changed and the result is probably more telegenic but is highly questionable (assassination of the couple instead of suicide Romy).
That said, the story is consistent with the reality of that time and great actors, especially Romy Schneider.
