Good 'A.I.' can be dangerous, great 'A.I.' can be deadly.

Rating: Null/10 (31 July 2015)

Written by a Brit, shot in England and Norway, with all non-American actors playing Americans. Interesting approach, and Norway is beautiful.
Domhnall Gleeson (using his best Jake Gyllenhaal accent) is hot-shot programmer Caleb, set some time in the near future, he works for the world's biggest internet-based company. There is a "competition" of sorts and he wins a trip to the big boss's home, with no idea why.
The big boss is Oscar Isaac as Nathan who wrote the original code when he was only 13, a real prodigy. But now he lives in a secluded place surrounded by mountains and valleys, in a house that is mostly underground. He welcomes Caleb but right away confronts him with a non-disclosure agreement to sign.
Nathan is eccentric but smart and inventive, and his reason to summon Caleb was to give a final test of his secret creation, a robot with artificial intelligence. Her name is Ava and she is played by pretty Alicia Vikander.
A note about the presentation of Ava. It was certainly filmed with "blue screen" techniques, the robot has some opaque, human-like features, but most of her legs, arms, and the back of her head are transparent, showing wires and cables inside. It is a very artistic presentation, and it made the actress believable as a robot.
So most of the movie centers on the interactions of these three characters, Caleb is never sure if Nathan is telling him everything, and Caleb finds out he didn't win a contest, he was chosen. At one point Ava tells Caleb that he can't trust Nathan. But can Ava be trusted?
Good, thought-provoking movie.
Edit: I watched it again April 2016, then again in October 2018, knowing the basic story made it an even more interesting movie, looking for the subtleties.
SPOILERS: Nathan's biggest weakness is a tendency to over-imbibe and get falling-asleep drunk at times. One time when he does Caleb steals Nathan's pass to grant access to all areas of the compound. Caleb finds old video of prior tests of robots that didn't work out, and in the process finds that he is attracted to Ava as if she really were human. He thinks he has hatched a plan for him and Ava to leave and lock Nathan in the compound, but Ava and another servant robot kill Nathan, change the codes and, as Ava leaves to find a crowded intersection to experience people Caleb is left trapped in the house, unable to break the glass to get out. You just can't trust artificial intelligence!
