Oscar winner Matthew McConaughey has announced the publication of his first book, a memoir titled Greenlights.
The book will be published by Penguin Random House on October 20. McConaughey shared the details with his followers in a video on social media.
The actor has described the book as "an album, a record, a story of my life so far".
"Ever since I learned to write, I've been keeping a journal. Writing down anything that turned me on, turned me off, made me laugh, made me cry, made me question or kept me up at night," he said.
"Two years ago I worked up the courage to take all those journals off into solitary confinement - just to see what the hell I had. And I returned with a book."
McConaughey said he chose the title Greenlights because "it's a story about how I have, and we all can, catch more of them in this life we're living".
"We don't like the red and yellow lights because they take up our time, right? But when we realise that they all eventually turn green, that's when they reveal their rhyme. That's when life's a poem and we start getting what we want and what we need at the same time."
In a statement about his "love letter to life", McConaughey added: "Hopefully, it's medicine that tastes good, a couple of aspirin instead of the infirmary, a spaceship to Mars without needing your pilot's licence, going to church without having to be born again, and laughing through the tears."
