NOTE: This review contains SPOILERS for the film (now playing widely in U.S. theaters).
Diane Ackerman’s non-fiction book was greatly inspired by the unpublished diary of Antonina Zabinska and Jan Zabinski, the director of the Warsaw Zoo in Poland. The book was published in 2007. While the real life events occurred in Warsaw, the movie was filmed entirely in Prague (w/ real baby lion cubs). This film also has a woman director (Niki Caro) and woman adapter (Angela Workman).
 It is still possible to find love and comfort in the darkest of times. Love is all around us. We must be the vessel through which hope and love spreads. Antonina believed this with her whole heart which is why she and Jan did what they did. There are brave people all around us: fighting for our rights, fighting for theirs, their family, their country – bravery comes in so many forms. This film reflects this: there is bravery in combat and ‘silent’ bravery. One is not greater than the other.
 One of the key messages seems to come from an early monologue delivered by Antonina where she compares the purity of animals (their eyes tell you everything) with the propensity to deceive and commonplace of ulterior motives in humans.
 Caro is able to reflect humanity, sincerity and earnestness in her films, which captivates and entangles the viewer. Caro’s directing prowess brings to mind the ideology of the male gaze vs. the female gaze in films… I feel as though I’m witnessing a life lived, purely, rather than someone’s perspective of that life.
-Excerpts from IMDB reviews
We first see Antonina (Jessica Chastain) as a happy figure riding her bike through a zoo with a young camel trotting beside her. She helps rescue a newborn elephant, interrupting a dinner party. But soon German bombs begin dropping on her city (Warsaw) and this zoo she runs w/ her zoologist husband, Jan (Belgian actor Johan Heldenbergh).
…she is undeniably captivating as the eponymous lead, channeling grit and vulnerability in equal measure as she fleshes out her character’s fears, anxieties and convictions. Among the supporting actors, Bruhl and Haas [the teenaged Israeli actress who plays a pivotal role] are the standouts, the former exercising admirable restraint in what could have been a traditionally villainous act, while the latter surprisingly nuanced in her portrayal…
-Excerpt from IMDB review
The scenes between Lutz Heck (Daniel Bruhl) and Antonina are tense; as he disarms her with his affinity/experience w/ of animals, BUT later scares her (and us) with his unwanted advances and desire to cross-breed animals in hopes of creating a new type of bison/bull (superior beast).
