Taking a quieter, more character-based view of the end of society, Margot Robbie shares the screen with two accomplished co-stars in a film that demands you pay attention from beginning to end.
The film takes place in the aftermath of a nuclear war that has ended society as we know it. Those who haven’t been killed by the blast struggle to survive the radioactive contamination. However, Ann (Robbie) has survived the catastrophic event thanks to living on a farm in a valley with favorable weather patterns that have sheltered her from the effects. Living a peaceful agricultural life with her dog, one day she stumbles upon John ( Chiwetel Ejiofor ) , a survivor whom she rescues from a contaminated lake and cares for.
The pair become close, until the arrival of Caleb ( Chris Pine ), a mysterious stranger who sparks John’s suspicions. The three learn to live together, with both men having their own different kind of bond with Ann. However, as tensions rise, it becomes clear something has got to give . The film was based on the 1974 novel by Robert C. O’Brien , and was mostly overlooked upon its theatrical release despite strong reviews from critics. However, the beauty of streaming is discovering hidden gems, and this is one that’s certainly worth your time.
Margot Robbie as Anne sitting by a piano in Z for Zachariah Image by Lionsgate When you think of movies that portray the end of the world, chances are you picture cities overrun with zombie swarms, climate disasters, or alien invasions. Director Craig Zobel’s film is different, in that the apocalypse that has left these characters alone happened in the distance, away from the events of the story. Instead, it focuses on how you survive and maintain your own humanity when so much of the world has been wiped out.
This greatly mirrors the 2009 award winner The Road , which focuses on the mental journey of its characters as much as physical survival. The script for Z for Zachariah asks how love, hope, and trust survive when everything has been taken away. It also mirrors Zobel’s 2012 debut, Compliance , which examines the mindset of people when driven by extreme circumstances. In looking at how three individuals survive the end of the world, we get a clearer connection to our own thoughts on what makes us human.
