They are not like people

I looked at the cover and thought this was a family movie of zookeepers and their lovely little zoo with a group of amazingly cute animals. Soon realized this was something completely different. A zoo, but a war-torn derelict one and the animals mostly slaughtered. Set in Warsaw in the beginning of WWII and the nazi occupation. Story of people trying to save as many jews from the Holocaust as possible. Reminiscence of Schindler's List, another true story, although not quite as emotionally stirring and, quite frankly, these people couldn't deliver such powerful omnipotent presence as people like Ralph Fiennes and Liam Neeson. But nevertheless enough an intesive piece of the harrowing times.
