The shoot for Niki Caro’s “The Zookeeper’s Wife,” starring Jessica Chastain, was an anomaly in how inclusive it was for women on set. Now the film’s first trailer has hit, detailing the period drama’s female-centric plot. We’ve heard of Oskar Schindler, and now we get to hear the story of a woman who went to similarly great lengths to save lives during the Holocaust.

As the official synopsis details, the film follows “the real-life story of one working wife and mother who became a hero to hundreds during World War II. In 1939 Poland, Antonina Żabińska (Chastain) and her husband, Dr. Jan Żabiński (Johan Heldenbergh), have the Warsaw Zoo flourishing under his stewardship and her care. When their country is invaded by the Nazis, Jan and Antonina are stunned — and forced to report to the Reich’s newly appointed chief zoologist, Lutz Heck (Daniel Brühl). To fight back on their own terms, Antonina and Jan covertly begin working with the Resistance — and put into action plans to save lives out of what has become the Warsaw Ghetto, with Antonina putting herself and even her children at great risk.”

“The Zookeeper’s Wife” featured a heavily female crew, so much so that, in 2015, Chastain published an essay via The Hollywood Reporter in which she expressed how much different it was to be on a set with mostly women. Shooting the film in Prague, Chastain wrote, “I’ve never been on a set with so many women. Usually on a movie it would be me and maybe two or three other women, even though there are 100 people there. It’s crazy.”

The script was written by Angela Workman (“War Bride”), based on the nonfiction book by Diane Ackerman.

Chastain is about to be fully entrenched in awards season. “Miss Sloane” has both a critically-acclaimed actress and a timely plot in its favor: the story centers on Elizabeth Sloane (Chastain), a ruthless, successful lobbyist who takes on the gun industry.

“The Zookeeper’s Wife” will hit theaters on March 31, 2017.
