Though you may know Matthew as Chris Merrill from the second season of Castle Rock, the actor was originally supposed to appear in the show's first season in a different role. "I was supposed to play one of the prison guards in season one, and about three days before filming was supposed to begin, I broke my foot on another job and I had to pull out," he explained to Daily Actor. Fortunately, he was able to land a much bigger role later on. "It was just a reminder to me to just let things happen the way they're supposed to happen," he added.
