Cube Zero is a 2004 Canadian independent psychological horror thriller film, written and directed by Ernie Barbarash. It is the third film in the Cube film series, being a prequel to the series.
Even though the first two films take place almost entirely within the maze, Cube Zero takes place in both the interior and exterior of the cube, as well as the aftermath. The film also reverts to the industrial-designed, colored rooms of the first film, but with a refreshed and redesigned set.
Reviews have been positive, claiming a more dramatic, and thrilling film in the series, but significantly less than Cube.
