Matthew McConaughey is known for his free-spirited, easy-going philosophy on life, as embodied in his famous catchphrase “Alright, Alright, Alright.” The actor first uttered those words in the movie Dazed and Confused and they have followed him through a long career in Hollywood, from romantic comedies to TV series to an Academy Award for Dallas Buyers Club. In this week’s “Sunday Sitdown,” Willie Geist gets together with McConaughey over Zoom to talk about that journey, and what it was like to reflect on it in his new book “Greenlights.”
