The Divide (2011) is a post-apocalyptic horror-thriller directed by Xavier Gens. The film is set in the aftermath of a devastating nuclear attack on New York City. A small group of survivors takes refuge in the basement of their apartment building, which is managed by the survivalist superintendent, Mickey (played by Michael Biehn).

As the group settles into the shelter, tensions rise, and their initial sense of relief quickly turns to despair. Confined in close quarters, they struggle with dwindling supplies, paranoia, and the psychological toll of their isolation. With no clear understanding of the outside world’s condition and little hope for rescue, the group slowly descends into chaos. As external threats and internal power struggles intensify, the survivors turn on one another in increasingly brutal ways, revealing the darkest sides of human nature.

The film’s grim atmosphere is punctuated by disturbing and violent moments as it explores themes of survival, desperation, and moral decay. As sanity begins to unravel, alliances shift, and the line between humanity and savagery blurs.

The Divide is known for its intense, claustrophobic setting and the raw performances of its cast, which includes Lauren German, Milo Ventimiglia, and Rosanna Arquette. Although the film received mixed reviews due to its graphic content and bleak tone, it is appreciated for its unflinching portrayal of the psychological horrors of survival in a post-apocalyptic world.
