Matthew McConaughey's chest pounding chant in the movie was not originally in the script! As seen in the film, he used it to gauge DiCaprio’s character completely out of the blue, and unsurprisingly it wasn’t in the script. In fact, it was actually a "relaxation technique" that McConaughey performed before each take. Leonardio Di Caprio noticed it and asked if it could be included in the scene. And that’s how Matthew’s personal relaxation technique became a piece of pop culture! Eugene Clark http://www.youtube.com/c/eugeneclark #Shorts
