Man and Machine Square Off in Tense 'Ex Machina' Trailer

Portishead's Geoff Barrow and composer Ben Salisbury handle the score for '28 Days Later' writer Alex Garland's upcoming sci-fi thriller

There's no god to save Domhnall Gleeson from this machine: The actor finds himself caught between man and robot in the intense new trailer for Ex Machina, a sci-fi thriller that marks the directorial debut of Alex Garland, the screenwriter behind 28 Days Later… and Sunshine.

Garland also wrote Ex Machina, in which Oscar Isaac (Inside Llewyn Davis) plays Nathan, a reclusive CEO who brings in Caleb (Gleeson) to test the capability and consciousness of a new artificial intelligent experiment. While Caleb is immediately impressed with this robot named Ava (played by Anna Karenina's Alicia Vikander), her intelligence and seductive nature reel him in even deeper. A new question arises: Who is really manipulating who? Ex Machina opens in theaters on April 10th, 2015.

The new movie also features a score from Portishead co-founder Geoff Barrow and Ben Salisbury, a longtime soundtrack composer, who has worked on a number of films and documentaries, including David Attenborough's Life Of... series and Beyoncé's Life is But A Dream. The pair also worked together on Dredd (which Garland also wrote), and in 2012 they released an album as DROKK on Barrow's Invada Records.

"It's been great for Ben and me to be working with [Director] Alex Garland again," Barrow said in a statement, "and hopefully we have written the kind of score an intense sci-fi thriller like this needs."
