In an interview with "Playboy", Damon expressed his displeasure with the changes, saying, "Everybody who worked on "All the Pretty Horses" took so much time and cared so much. As you know, the Cormac McCarthy book is set in 1949 and is about a guy trying to hold on to his old way of life. The electric guitar became popular in 1949, and the composer Daniel Lanois got an old 1949 guitar and wrote this spare, haunting score. We did the movie listening to his score. It informed everything we did. We made this very dark, spare movie, but the studio wanted an epic with big emotions and violins. They saw the cast, the director, Billy Bob Thornton, and the fact that we spent $50 million, and they never released our movie—though the cut still exists. Billy had a heart problem at that time, and it was because his heart fucking broke from fighting for that film. It really fucked him up. It still bothers me to this day."
