"Zero Dark Thirty" star Jessica Chastain is all set to star in "The Zookeeper's Wife", the adaptation of 2007 novel by Diane Ackerman.
Niki Caro will direct the World War II story, which is being produced by Panorama, the Hollywood Reporter said.
"The Zookeeper's Wife" is the true account of keepers of the Warsaw Zoo, who helped save hundreds during the Nazi invasion.
When the Nazi army overran Warsaw, destroying the city and its zoo, Jan and Antonina Zabinski began smuggling Jews into empty cages.
