When character Rust Cohle (Matthew McConaughey) asks for a beer while being interviewed he does this not only because he is a functioning alcoholic but also because he now can rest assured anything he says is inadmissible in court.
According to the show's creator, Nic Pizzolatto, Matthew McConaughey "has this incredibly complicated chart of where Rust Cohle is emotionally and physically at every beat of those 17 years."
Rust says he remembers the day they found the dead body because it was the day of his daughter' birthday, January 3rd, and that's the same day Matthew McConaughey's daughter Vida was born in 2010.
Each season of the show will be centered around a new story, mystery and cast.
In this episode and several others, Matthew McConaughey's character drinks beers called Lone Star while being interviewed. Lone Star Beer is from The Lone Star State of Texas. McConaughey was in a film in 1996 called Lone Star. Both his character in Lone Star and True Detective are in law enforcement.
