Before watching this movie, I went to Rabe's house in Nanjing and I read his diary. I was surprised that the movie does not match with the diary. Important parts are missing, and there are even contradictions at some points. For example: according to the diary, Rabe's wife Dora is outside Nanjing before the Japanese invasion starts. In the movie, Dora is still in Nanjing. And when it comes to the date that Rabe leaves Nanjing, there's also a couple of months difference between the diary and the movie. It seems as if the movie producers wanted to 'dramatize' the original story. I don't understand why. Rabe's diary is dramatic enough. My advice is to skip the movie, and read the diary instead.
