Watch In a Box (1968) Official Trailer

There are three boxes in the same sphere. In one box, a human figure is having trouble fitting in. Sometimes he tries to conform, sometimes he tries to escape, and sometimes he just tries to do what he wants despite the box. In the next box, another figure is always trying to force the person in box one into whatever form that box is taking. And the last box is a television, which is cheering the other two on.
