I saw Schindler’s List when it was released, can’t believe it was 1993, and apart from the slightly laboured points (which I didn’t really notice back then) I think it holds up as the best effort to bring this history to a wider audience.
But I remember hearing an interview by Ralph Fiennes who played Amon Goeth. While he was resting on-set in Poland, wearing the SS uniform of the character he played, an old woman came up to him and said that she thought it was a good thing that the Nazis had done what they did to the Jews in Poland!
The Holocaust is certainly a rich theme for movie-making, not really anti-war as such, more of a sub-category in war-movies.
Off the top of my head I can think of The Pianist (which I didn’t really like), Shoah (which is brilliant if you have ten hours to spare), Playing for Time and Life Is Beautiful (that won three Oscars).
