Bella Tarr has apparently found a way to make a movie without hiring an editor. There is a theory - I think Tarkovsky - that if you hold a shot beyond where people are bored or uncomfortable, they will become fascinated. Tarr has taken that to an extreme. He has tried to make a "Work of Art" by simply making a long movie. My guess is that a filmmaker with a normal film economy would have made it about 100 minutes. For Bresson, it would have been a 50-60 minute film.
