The perfect murder does exist.
The Assignment, from writer and director James Cunningham, is a short film currently in pre-production and rehearsal stages.
The film follows two mates, Harrison (Dave Kara) and Leo (Francis Ryan), both of whom has been pitted an assignment from their University professor. Harrison is studying criminology and psychology and his assignment is to plan the 'perfect murder'. It's an exercise in hypothetical criminal theory and it sparks a debate/conversation between Harrison and his mate Leo.
The film features a bloody ending in a scene eerily reminiscent of the famous shower scene from Alfred Hitchcock's Psycho (1960). But has Harrison done this before?
