I don't know if you ever seen it, but "Uprising" is also a great television movie which deals with the resistance of Jews in the Warsaw Ghetto. Hank Azaria turns in a tour-de-force!

The Hiding Place.
This was a great film focusing on the heroic actions of Corrie ten Boom and her family, who were the spitting definition of "righteous gentiles."
Anne Frank wasn't the only brave person in Holland at that time.
I’ve read a few books about the Warsaw uprising, and the heroism never fails to affect me. They definitely had the odds against them - but it was better than dying like slaughtered farm animals.
