The Japanese man who saved 6000 Jews with his handwriting

I saw this by David Wolpe in The New York Times and wondered, how would this be a film?

I can see the obvious parallel to Schindler’s List (1993), although Chiune Sugihara’s story doesn’t have a list to focus the narrative. Sugihara doesn’t change in the way Schindler does, he remains steadfast despite the pressure to conform. The question to be answered is what are the stakes, what does he want? Something to think about.
