Cube is a 1997 Canadian science fiction psychological horror film, directed and co-written by Vincenzo Natali. The film was a successful product of the Canadian Film Centre's First Feature Project.
A man named Alderson (Julian Richings) awakens and finds himself in a cube-shaped room with a hatch in each wall, the floor, and the ceiling. Opening some of the hatches, he finds passages to rooms that are identical except for their colors. He enters an orange room and, without warning, is sliced to pieces by a wire grill which kills him instantly.
In another such room, five people - Quentin, Worth, Holloway, Rennes, and Leaven - meet. None of them knows where they are or how they got there. Quentin informs the others that some cubes contain traps, which he learned by nearly being killed by one.
