Chigurh stares unblinking at the gas station clerk while the coin flip is decided.
Bardem keeps a flat, dead-on gaze that never wavers. The stillness of his eyes contrasted with the small head movements creates dread. Beginners can study how zero blinking changes the temperature of a room.
What to observe
Practice Guide (5 steps)

Stand tall and focus your gaze on a point in front of you, like a spot on the wall. Try to hold your gaze without blinking for 10 seconds, allowing your eyes to remain wide and attentive.
Pro tip: Practice in front of a mirror to observe your eye movement and ensure you maintain a steady posture.

Select a partner or an object and maintain eye contact while you ask a question. Ensure your gaze does not waver as you listen to the response.
Pro tip: Notice how your body feels when you maintain this contact; it can help you become more aware of the tension it creates.

Record yourself maintaining eye contact with a partner and briefly narrow your eyes as if you are evaluating their response. This should be subtle but noticeable.
Pro tip: Focus on the emotional impact of your gaze; micro-expressions can significantly alter the interaction's dynamics.

Look directly at an object or person and hold your gaze even after they look away. Count to five in your head before breaking your gaze.
Pro tip: This technique builds suspense; try it in different scenarios to see how it changes the atmosphere.

Simulate a decision-making scenario by flipping a coin while maintaining eye contact with it and an imagined audience. Focus on both the coin and the audience as the coin flips.
Pro tip: This helps express intensity; ensure your expression remains neutral to underscore the stakes of the moment.
