Geometrically suspenseful, methodically haunting.
Using the Turing Test as both subject matter and filmmaking approach, writer/director Alex Garland crafts a methodical, seemingly clinical, ultimately human (or at least, humanly messy) examination of what it is to be human. The geometry of Rob Hardy‘s cinematography showcases the incremental precision of the three lead performances from Alicia Vikander as the AI Ava, Domnhall Gleeson as Caleb, and a terrifying Oscar Isaac as Nathan (who also, together with Sonoya Mizuno, gifts us with that dance sequence)… what a claustrophobic, haunting good time.
Thomas Flight examines Ex Machina as a Turing Test – not for Caleb (Domnhall Gleeson), but for the viewer:
I don’t think this is a secret or even subtle element of the film – much in the same way Nathan says the point is that Caleb knows from the beginning that Ava is a machine, the film tells us where it’s going almost immediately, and the enjoyment is in seeing how it gets there.
