I enjoyed The Zookeeper's Wife and would recommend it to most audiences. Skillful direction by Niki Caro, excellent sets and costumes, a slightly washed-out look to the cinematography which nonetheless has a full range of color, and a capable cast. The story is based on the actions of the owners of the Warsaw Zoo, who saved the lives of more than three hundred Jews during the Nazi occupation of Poland.
Nonetheless, the performance of Jessica Chastain is the single most important factor in the film. Unlike many American actors, she understands that a Polish woman of the 1940s does not look, move, or carry her features like a contemporary American. So fully does Miss Chastain inhabit her character that I never had the sense of an actress making choices.
The film is a bit long and a bit slow, like most films today, but not to a damaging extent. I particularly admired the way that the official from the Berlin Zoo who becomes a Nazi officer, well played by Daniel Bruhl, has certain scruples and personal moral standards although he embraces the Nazi philosophy. He's a villain, but not a cardboard villain, and part of the suspense of the film is waiting to see which lines he will cross and which he won't.
