What are the most compelling films depicting the Holocaust?

I just watched The Pianist, which I thought was breathtaking. I would like to watch similar films that depict the Holocaust or events surrounding the Holocaust because I am interested in History and also the emotion in these movies is incredibly moving.

I've also seen Schindler's List, The Lives of Others, Inglorious Basterds, Napola...and maybe some others I can't remember. Hoping to see Downfall soon too.

Any other suggestions?
