When filming Rope (1948), Alfred Hitchcock intended for the film to have the effect of one long continuous take, but the cameras available could hold no more than 1000 feet of 35 mm film.
Andy Warhol and collaborating avant-garde filmmaker, Jonas Mekas, shot the 485-minute-long experimental film, Empire (1964), on 10 rolls of film using an Auricon camera via 16mm film which allowed longer takes than its 35 mm counterpart.
