Following the featurette released last month, the first clip has debuted from A24 Films' Ex Machina. This intense psychological thriller centers on Caleb (Domhnall Gleeson), a 24 year old coder at the world's largest internet company, who wins a competition to spend a week at a retreat belonging to the company's reclusive CEO, Nathan (Oscar Isaac). But when Caleb arrives he finds that he will have to participate in a fascinating experiment with the world's first true artificial intelligence, housed in the body of a beautiful robot woman, Ava (Alicia Vikander). Truths, emotions and motives are blurred as the relationship between Caleb, Ava and Nathan intensifies.

Caleb's job is to perform a "Turing Test" (named after The Imitation Game subject Alan Turing) on Ava, to determine whether or not this A.I. being has actual consciousness. Alex Garland, who has written films such as 28 Days Later, Sunshine and Dredd 3D, makes his directorial debut with this sci-fi thriller, explaining in an interview with Yahoo! Movies U.K. that he wanted to present Ava as robotic as possible.

"That was absolutely the idea. The key thing is that you present her as beautiful, elegant and strange, but most of all you present her as a machine. You begin with something you wouldn't attribute sentience to, and then show that it's there. The film essentially tracks the relationship between this young guy and this robot girl. Both of them - and, separately, Oscar - has to track the emotional arc very closely, to make sure they're in the right place at any given moment."
