One of a small number of (film/TV) productions featuring truly lifelike humanoid AIs, played obviously by actual humans. This highly watchable film charts the final stages in a journey taken to create such entities. It goes the whole hog and explicitly envisages the emergence of sentience in its creations, wrapping this up in a ‘real-life’ Turing Test. Mimicking, unconsciously, the way that complexity ruined the best-laid plans in Jurassic Park, one of the humanoids duly foils its creator’s intentions in Ex Machina. An intense, disturbing, must-see film.
