»In my ‘total theater,’ I not only envisioned the option of film projection for the three deep stages onto the entire cyclorama with the aid of a system of movable film projectors, I also plan to project films onto the walls and ceilings of the entire auditorium. . . . The projection room takes the place of the previous projection level (cinema)«
