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 and in the floor and 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.
In another such room, five people - Quentin, Worth, Holloway, Rennes and Leaven - meet. None know where they are, how they got there, or why. Quentin, having almost been killed by one, informs them that some cubes contain traps.
