Of historical note, this was the first Hollywood film to show footage of the Holocaust. (There is one scene they show it.) This was from the same footage that was used in the Nuremberg Trials.
This is what Orson Welles wrote about it:
No, you must not miss the newsreels. They make a point this week no man can miss: The war has strewn the world with corpses, none of them very nice to look at. The thought of death is never pretty but the newsreels testify to the fact of quite another sort of death, quite another level of decay. This is a putrefaction of the soul, a perfect spiritual garbage. For some years now we have been calling it Fascism. The stench is unendurable
Thanks for posting that quote.
Welles was an eloquent man.
