How to watch Ex Machina
2015 · Alex Garland · Ex Machina on Sightlines
5 things to watch and listen for on a first viewing, without spoilers, and 4 more once you have seen it. Each names something you can see or hear, the pattern it belongs to, and what noticing it gives you. How these keys work.
On a first viewing
Watch the curved glass between Caleb and Ava catch reflections. (camera)
Hardy keeps finding the moment the partition turns mirror: Ava's face over Caleb's reflection, Caleb ghosting across her open chest. Glass walls, mirrors, and her transparent torso repeat the effect all film.
Payoff: You stop being able to tell the body from the picture of a body, which is exactly the film's question. In the reading: the crystal-image (hyalosign). The reading calls these crystal-images: shots where a thing and its reflection stop being separable.
Watch the glass walls and doors that divide the house. (staging)
Nathan moves through the whole facility. Caleb gets a room and a route. Ava gets a glass cell. The architecture assigns each a permitted range.
Payoff: Power in this house is not spoken. It is built into the floor plan.
Look at Vikander's face in the pauses between Ava's lines. (performance)
She holds stillness and lets micro-expressions gather without resolving them. You cannot settle whether Ava feels, performs feeling, or performs not feeling. The long takes refuse to cut away and let you off.
Payoff: The film stakes its entire uncertainty on one face, and never tells you how to read it. In the reading: icon of power (potisign). The reading calls this a potisign: a face building intensity that never discharges into a fixed expression.
Listen for the soft mechanical clicks when Ava moves. (sound)
Salisbury and Barrow's score sits under everything as drones and low pulses that never resolve into melody. Ava's servos live at the same low level, just audible, just slightly wrong.
Payoff: The unease is delivered at the edge of hearing, so it never announces itself as horror.
Watch for the session numbers that appear on screen. (structure)
Garland breaks the week into numbered Turing sessions, giving a seduction the rhythm of a lab experiment. Between them, time skips and Caleb's agitation grows offscreen.
Payoff: The numbering keeps insisting this is a controlled test, which makes you ask who set the controls.

Carry this in: Watch the glass. Every time it catches a reflection, ask which side you are standing on.
