Many years ago I worked for a film-maker who had a decidedly rule-breaking approach to his work: he would just let his running camera swing from a strap in his hand. His takes were as long as the camera wind would last; his films as long as the film in the camera would last (IIRC, he used both a Bolex H16 and a Bell and Howell Filmo.) Needless to say, given his "aesthetic", the films were projected uncut. I once suggested that he would save time and money if he just projected the film also unprocessed. And, needless to say, we parted company soon after that.
