Alfred Hitchcock films would be agony to that crowd. The opening shot for his film "Rope" clocks in at about 9 and a half minutes. All in a single shot!
Back then, there were no such studio cameras to continuously record to film reels over a certain length.
Russian Ark (2002) (Russian: Русский ковчег) is a single 96-minute steadicam shot, and it has over 2,000 actors and three orchestras in it. It was recorded directly to a hard drive carried behind the camera operator, which could hold 100 minutes.
