Det. Rust Cohle has become the subject of countless memes and online parodies in the past months. But to prepare for the character’s shell-shocked cynicism and existential philosophizing, McConaughey underwent the kind of immersive and obsessive preparation one might expect from a recent Oscar-winner – and even from the fictional detective himself.
Business Insider reports that McConaughey prepared by assembling a massive book-sized graph, which charts Rust’s character arc from over the span of 17 years. “I just basically broke it down and made a 450-page graph of where Cohle was and where he was coming from,” McConaughey said.
