Cube 2: Hypercube

CubeHypercube is a 2002 Canadian science fiction psychological thriller film and the sequel to Cube. Released in 2002, CubeHypercube had a different director than its predecessor, Andrzej Sekua. The industrialstyle rooms of the first film are replaced with hightech, brightly lit chambers instead of traps such as flamethrowers and extending spikes, the rooms have evolved and now are controlling illusion, time, space and reality.

Some time later, a woman named Kate Kari Matchett, detective Simon Geraint Wyn Davies, a blind girl named Sasha Grace Lynn Kung, engineer Jerry Neil Crone, game developer Max Matthew Ferguson, lawyer Julia Lindsey Connell, and an elderly woman named Mrs. Paley Barbara Gordon find themselves trapped in brightly lit cubes, each with a panel on each of the six sides, which are doors to other rooms. They come across Colonel Thomas Maguire Bruce Gray, who says that they have to solve the code in order to leave the mysterious place. A wall begins to close in on the group. The group escapes while Thomas stays behind. Kate and Simon watch in horror as Thomas is disintegrated by the wall. Later experiences around the cube reveal that gravity can operate in different directions in each room, while Mrs. Paley revealed to be a retired theoretical mathematician and Jerry realize that they may be in a tesseract, or a hypercube. Kate notices the numbers 60659 everywhere they go.The group realizes they are connected to Izon, a defense contractor. Mrs. Paley opens a panel to reveal her and Simon being killed. Jerry thinks that it is a parallel universe, while Max and Julia think it is an optical illusion. Later, while the group is sleeping, Simon realizes that he is in the tesseract to look for Becky, a missing Izon worker. Meanwhile, Sasha, who has acute hearing, hears a noise and awakens everyone. The group finds a floating square in the middle of the room which initially grows into several shifting variations of a tesseract, before expanding into a lethal and rapidly spinning frame. ........
