Yeah, I was actually looking for that movie recently (there is also some movie about Nanking Massacre particularly, "Nanjing! Nanjing!").
Another interesting story about a person who saved even more lives than Schindler: http://www.imdb.com/title/tt1010278/
Although I haven't seen this one yet (got dubbed version, which is something unacceptable ;| I mean wtf they always dub only movies for kids), rating is quite good. Assisted by some two dozen other Zegota members, Sendler saved 2,500 Jewish children by smuggling them out of the Warsaw Ghetto, providing them with false documents, and sheltering them in individual and group children's homes outside the Ghetto.
