Cube Zero is a 2004 Canadian horror film, written and directed by Ernie Barbarash. It is the third of the Cube films, and its plot builds on the previous two in the sense that it is primarily about people who are trapped within a maze of cube-shaped rooms, with some of the rooms containing deadly traps. Whereas the first two films take place almost entirely within the maze, Cube Zero takes place within and outside the maze, making significant use of outdoor scenes.
