Realistically, no one can watch the whole of «24 Hour Psycho», which consists of Alfred Hitchcock’s film «Psycho» (1960) slowed down so that a single, continuous viewing lasts for twenty-four hours. While we can experience narrative elements in it (largely through familiarity with the original), the crushing slowness of their unfolding constantly undercuts our expectations, even as it ratchets up the idea of suspense to a level approaching absurdity.
