When German soldiers take over the Warsaw Zoo, Antonina Zabinski (Jessica Chastain) and her husband do what they can to save themselves and others in “The Zookeeper’s Wife.” (AP) By M. Scott Morris Daily Journal “The Zookeeper’s Wife” isn’t entertaining so much as transportive. It’s a heroic tale set amid one of humanity’s worst moments, and the tragedies it depicts can be difficult to watch. Jessica Chastain plays Antonina Zabinski, wife of the director of the Warsaw Zoo in the days leading up to the Nazi invasion of Germany. Her husband, Jan (Johan Heldenbergh), wants Antonina to leave the city with their son, and the viewer knows what trouble awaits them when she talks him into letting her stay. The zoo is a delightful place.
