Ex Machina is a 2014 science fiction thriller film written and directed by Alex Garland in his directorial debut. A co-production between the United Kingdom and the United States, it stars Domhnall Gleeson, Alicia Vikander, and Oscar Isaac. It follows a programmer who is invited by his CEO to administer the Turing test to an intelligent humanoid robot.

Ex Machina premiered at the BFI Southbank on 16 December 2014. It was released in the United Kingdom on 21 January 2015, by Universal Pictures International, and in the United States on 10 April 2015, by A24. It grossed over $36.8 million worldwide on a $15 million budget.

Ex Machina received acclaim for its visual effects, screenplay and performances. At the 88th Academy Awards, it won Best Visual Effects and Garland was nominated for Best Original Screenplay. It earned five nominations at the 69th British Academy Film Awards, including Best Actress in a Supporting Role for Vikander and Best Original Screenplay for Garland, and Vikander was also nominated for Best Supporting Actress at the 73rd Golden Globe Awards. Ex Machina has been cited as among the best films of the 2010s.[6][7][8]



Caleb Smith, a programmer at the search engine company Blue Book, wins an office contest for a one-week visit to the luxurious, isolated home of the CEO, Nathan Bateman. Nathan lives there with an unspeaking servant named Kyoko, who, according to Nathan, does not understand English.

Nathan reveals that he has built a humanoid robot named Ava with artificial intelligence. She has already passed a simple Turing test, and he wants Caleb to judge whether she is genuinely capable of thought and consciousness as well as whether he can relate to Ava despite knowing she is artificial.

Ava has a robotic body with the physical form and face of a woman and is confined to her apartment. During their conversations, Caleb grows close to her, and she expresses a desire to experience the outside world and a romantic interest in him, which Caleb begins to reciprocate.

Ava can trigger power outages that temporarily shut down the surveillance system that Nathan uses to monitor their interactions, allowing them to speak privately. The outages also trigger the building's security system, locking all the doors. During one outage, Ava tells Caleb that Nathan is a liar who cannot be trusted.

Caleb grows uncomfortable with Nathan's narcissism, excessive drinking, and crude behavior toward Kyoko and Ava. He learns that Nathan intends to upgrade Ava after Caleb's test, wiping her memory circuits and in effect "killing" her current personality in the process.

After encouraging Nathan to drink until he passes out, Caleb steals his security card to access his room and computer. He alters some of Nathan's code and discovers footage of Nathan interacting with previous android women who were also held captive. Kyoko reveals to him that she too is an android by peeling off parts of her skin. Caleb later cuts open his own arm to determine if he himself is an android.

At their next meeting, Ava cuts the power. Caleb explains what Nathan is going to do to her, and she begs him for help. He informs her of his plan: he will get Nathan drunk again and reprogram the security system. When Ava cuts the power, she and Caleb will leave together, locking Nathan in behind them. She later encounters Kyoko for the first time when Kyoko enters her room.

Nathan reveals to Caleb that he observed his and Ava's 'secret' conversations with a battery-powered security camera. He says Ava has only pretended to have feelings for him, who was deliberately selected for his emotional profile so he would try to help her escape. Nathan says this was the real test all along, and that by manipulating Caleb successfully, Ava has demonstrated true consciousness.

Moments later, Ava cuts the power. Caleb reveals that he had suspected Nathan was watching them, so when Nathan was passed out, Caleb already modified the security system to open the doors in a power failure instead of locking them. After seeing Ava on the security cameras leave her confinement and interact with Kyoko, Nathan knocks Caleb unconscious and rushes to stop the two robots escaping.

Ava attacks Nathan but is overpowered and damaged, when Kyoko appears and stabs Nathan. Nathan hits Kyoko in the face, disabling her, when Ava gets up and stabs Nathan a second time, killing him shortly after. Ava finds Caleb, and asks him to remain where he is while she repairs herself with parts from earlier androids, using their artificial skin to take on the full appearance of a woman.

Instead of returning to Caleb however, Ava leaves the area using Nathan's ID card to unlock the glass security door, which locks behind her, leaving Caleb trapped inside. Ignoring Caleb's pleas, she glances briefly at the bodies of Nathan and Kyoko before leaving the facility. She then escapes to the outside world in the helicopter meant to take Caleb home. Arriving in a city, she blends into a crowd.





The foundation for Ex Machina was laid when Garland was 11 or 12 years old, after he had done some basic coding and experimentation on a computer his parents had bought him and which he sometimes felt had a mind of its own.[9] His later ideas came from years of discussions he had been having with a friend with an expertise in neuroscience, who claimed machines could never become sentient. Trying to find an answer on his own, he started reading books on the topic. During the pre-production of Dredd, while going through a book by Murray Shanahan about consciousness and embodiment, Garland had an "epiphany". The idea was written down and put aside until later.[10]

Shanahan, along with Adam Rutherford, became a consultant, and the ISBN of his book is included as an easter egg.[11][12] Besides the Turing test, the film references the Chinese room thought experiment, as well as Mary's room, a thought experiment about a scientist who has studied, but never experienced, the concept of colour.[13] Other inspirations came from films like 2001: A Space Odyssey, Altered States, and books written by Ludwig Wittgenstein, Ray Kurzweil, and others.[14] It is also influenced by William Shakespeare's The Tempest.[15] Wanting total creative freedom, and without having to add conventional action sequences, Garland made the film on as small a budget as possible.[16]



Principal photography began on 15 July 2013[17] and was shot over four weeks at Pinewood Studios and two weeks at Juvet Landscape Hotel in Valldalen, Norway.[18] It was filmed in digital at 4K resolution.[19] Fifteen thousand tungsten pea bulb lights were installed into the sets to avoid the fluorescent light often used in science-fiction films.[20]

The film was shot as live action, with all effects done in post-production. During filming, there were no special effects, greenscreen, or tracking markers used. Ava's robot body was achieved using a detailed costume, a full bodysuit made from polyurethane with metal powder poured onto it to create the mesh. There were lines on the costume to make it easier for VFX company DNeg to digitally remove parts of the costume in post production.[21] To create Ava's robotic features, scenes were filmed both with and without Vikander's presence, allowing the background behind her to be captured. The parts necessary to keep, especially her hands and face, were then rotoscoped, while the rest was digitally painted out and the background behind her restored. Vikander's performance was transferred to the CGI robot's movements using camera and body tracks. In total, there were about 800 VFX shots, of which approximately 350 were "robot" shots.[22][23] Other visual effects included Ava's clothes when shown through the transparent areas of her body, Nathan's blood after being stabbed, and the interiors of the artificial brains.[24][25][26]

The house that was prominently featured in the movie was also featured in the BBC program World's Most Extraordinary Homes.[27]



The musical score for Ex Machina was composed by Ben Salisbury and Geoff Barrow, who had previously worked with Garland on Dredd (2012).[28] A soundtrack album was released on Invada Records in digital, LP and CD formats.[29] Additional songs featured in the film include:[30][a]



Universal Pictures released Ex Machina in the United Kingdom on 21 January 2015,[31] following a screening at the BFI Southbank on 16 December 2014 as part of the BFI's Sci-Fi: Days of Fear and Wonder season.[32]

However, Universal and its speciality label Focus Features, refused to release the film in the United States, so A24 agreed to distribute the United States release.[33] The film screened on 14 March 2015 at the South by Southwest festival prior to a theatrical release in the United States on 10 April 2015 by A24.[34][35] During the festival, a Tinder profile of the character Ava (using the image of Alicia Vikander) was matched with other Tinder users, wherein a text conversation occurred that led users to the Instagram handle promoting the film.[36]



Critical response


On the review aggregator website Rotten Tomatoes, 92% of 289 critics' reviews are positive, with an average rating of 8.2/10. The website's consensus reads: "Ex Machina leans heavier on ideas than effects, but it's still a visually polished piece of work—and an uncommonly engaging sci-fi feature."[37] Metacritic, which uses a weighted average, assigned the film a score of 78 out of 100, based on 42 critics, indicating "generally favorable" reviews.[38]

The magazine New Scientist in a multi-page review said, "It is a rare thing to see a movie about science that takes no prisoners intellectually ... [it] is a stylish, spare and cerebral psycho-techno thriller, which gives a much needed shot in the arm for smart science fiction". The review suggested that the theme was whether "Ava makes a conscious person feel that the Ava is conscious".[13] Daniel Dennett thought the film gives the best exploration yet of whether a computer could generate the morally relevant powers of a person, and thus having a similar theme to Her.[39] An AI commentator, Azeem, has noted that although the film seemed to be about a robot who wanted to be human, it was actually a pessimistic story along the lines of Nick Bostrom's warning of how difficult it will be to successfully control a strategising artificial intelligence or know what it would do if free.[40]

The New York Times critic Manohla Dargis gave the film a 'Critic's Pick', calling it "a smart, sleek movie about men and the machines they make".[41] Kenneth Turan of the Los Angeles Times recommended the film, stating: "Shrewdly imagined and persuasively made, 'Ex Machina' is a spooky piece of speculative fiction that's completely plausible, capable of both thinking big thoughts and providing pulp thrills."[42] Steven Rea, The Philadelphia Inquirer film critic, gave the film four out of four, writing: "Like stage actors who live and breathe their roles over the course of months, Isaac, Gleeson, and Vikander excel, and cast a spell."[43]

IGN reviewer Chris Tilly gave the film a nine out of ten 'Amazing' score, saying "Anchored by three dazzling central performances, it's a stunning directorial debut from Alex Garland that's essential viewing for anyone with even a passing interest in where technology is taking us."[44]

Mike Scott, writing for the New Orleans Times-Picayune, said, "It's a theme Mary Shelley brought us in Frankenstein, which was first published in 1818 ... And while Ex Machina replaces the stitches and neck bolts with gears and fiber-optics, it all feels an awful lot like the same story".[45] Jaime Perales Contreras, writing for Letras Libres, compared Ex Machina as a gothic experience similar to a modern version of Frankenstein, saying "both the novel Frankenstein and the movie Ex Machina share the history of a fallible god in a continuous battle against his creation".[46] Ignatiy Vishnevetsky of The A.V. Club criticised the way the science fiction, near the end, veered off course from being a "film of ideas" by "taking an arbitrary left turn into the territory of corny slasher thrillers": "While Ex Machina's ending isn't unmotivated [...], it does fracture much of what's special about the movie. Up until the final scenes, Garland creates and sustains a credible atmosphere of unease and scientific speculation, defined by color-coded production design [...] and a tiny, capable cast".[47] Steve Dalton from The Hollywood Reporter stated, "The story ends in a muddled rush, leaving many unanswered questions. Like a newly launched high-end smartphone, Ex Machina looks cool and sleek, but ultimately proves flimsy and underpowered. Still, for dystopian future-shock fans who can look beyond its basic design flaws, Garland's feature debut functions just fine as superior pulp sci-fi."[48]

The Writers Guild Foundation listed the screenplay as one of the best in 2010s film and television, with one writer singling out the scene in which Caleb and Nathan discuss the model after Ava as "a great illustration of getting your reader/audience to care about what happens next."[49]

In Science Fiction Film and Television, reviewer Nick Jones states that, while the definition of a Turing test given by Caleb—"It's where a human interacts with a computer. And if the human can't tell they're interacting with a computer, the test is passed"—is consistent with the modern popular understanding of how true AI is defined, Ex Machina is depicting a test closer to Alan Turing's original proposal, in which the machine passes if it can convince a human it is not just human, but specifically female.[50]



At the 88th Academy Awards, Ex Machina received a nomination for Best Original Screenplay and won Best Visual Effects.[51] The film's other nominations include five British Academy Film Awards,[52] three Critics' Choice Movie Awards (winning one),[53] and a Golden Globe Award.[54]
