But even as his creativity blossomed, his heavy drug use took a toll, leading to a period of destructive behavior and the failure of his first marriage. It was June Carter (Reese Witherspoon), daughter of the first family of country music, who lifted Cash out of his emotional chaos and helped him to become the man and the musician he was meant to be.
