Matthew McConaughey and Woody Harrelson
Matthew and Woody have worked on a couple of projects together, and that’s probably where they bonded. In 2013, when Matthew got the role in True Detective, he asked the director to give the second part to Woody. While they were shooting, they’d meet on Sunday at someone’s place and read the script together, and one would coach the other on the best way to play the character.
Many years later, they are still best friends and even go on a “friendship tour” every year, traveling with a couple of other friends.
