A prisoner had escaped from his cell block and so, someone had to be punished. A prisoner was randomly chosen to die by starvation for this transgression. Max said - take me instead. Unlike the man who was selected, Max had no family. His story is quite remarkable and by all means, learn more about Maximilian Kolbe.
In honor of Max Kolbe, we recommend two movies. First - Escape from Sobibor starring Alan Arkin and Rutger Hauer. Sobibor was a concentration camp in Poland and unfortunately, not enough people have ever heard of what transpired there. It is an amazing movie about one of the greatest prisoner escapes in WWII. Just watch it. It's an A+ film of a heroic story, just like Max Kolbe's life. Second - we suggest Roberto Rossellini's Open City, which is another powerful World War II story, this time set in Rome. In this movie, Aldo Fabrizi plays a heroic Catholic priest. It also stars Anna Magnani.
