Big Wednesday (1978)

Exit 8 is adapted from the popular game with the same name (The Exit 8), starring beloved actors Kazunari Ninomiya and Nana Komatsu. The setting is rather simplistic: the supposed passage to the subway exit turns out to be an endless loop, like the shape of 8. One has to follow the rules, which are written on a regular sign on the wall, in order to go out: If ‘an anomaly’ is spotted, turn back; if not, keep walking in the same direction. When the protagonist picks the right choice, the number of the exit’s name by the side of the game rule sign will increase (from Exit 0 to Exit 1, etc.). Otherwise, the number will return to 0.
