In this clip, Christopher Nolan uses a number of screen forces within "The Prestige." The clip opens with Christian Bale at a desk sitting and writing some notes. His particular form uses psychological closure to create a triangular shape that is both familiar and pleasurable to the eye. At around 0:32, Bale's character also tosses a ball into the air while following it with his eyes. The ball works as a motion vector while his eyes are the index vector. Forces full strongly to the top frame.
