Alex Garland is no stranger to science fiction. As the writer of 28 Days Later and Sunshine, he's given us his own unique spin on the zombie apocalypse and a last-ditch effort to save the Earth (by nuking the sun!). Now, with his directorial debut, Ex Machina, Garland is taking on artificial intelligence -- and in the process, he shows the limits of the Turing test, the most common method for determining if something is truly sentient. The film centers on a young programmer who's sent to his genius CEO's isolated compound to test his latest invention: an artificially intelligent robot. Things, as you can imagine, don't go as planned.
