Cube (1997) dir. Vincenzo Natali

Seven strangers must find a way out of a seemingly endless and deadly puzzle – a giant cube building with thousands of rooms. Original and thrilling psychological horror mixed with science fiction and mathematics. Well selected characters and a talented cast have given Cube a cult status. A great exploration into the depths of human nature, rolled into a thrilling and simple conceptual plot. A Kafkaesque film of great mystery and suspense in every scene.
“Fear, Paranoia, Suspicion, Depression.”
Low-budget masterpiece and beginning of a trilogy from Candian-American Vicenzo Natali in his directorial debut. The story is inspired by an episode of the Sci-Fi classic show, The Twilight Zone.
