Ruggero Eugeni argues that film profited from an insistent reference to hypnosis. If in early depictions, hypnotists were pointing their fingers at the subject in order to hit him or her with a shot of magnetic fluid, by the early twentieth century, subjects were induced into a hypnotic state as the hypnotist’s hand waved repeatedly in front of the eyes. This new gestural format, repeatedly staged by the movies of the same period, was instrumental in mirroring and shaping in imaginary terms the film’s screening conditions and the viewer’s experience. At a moment when a nascent inema might have been defined in a number of ways, the anachronistic figure of the hypnotist’s hand worked to establish the screen rather than the film or the projector as the essential element of an emerging assemblage.
