This is a very useful article in which I found an interview taken just before the release of "The Amityville Horror" in April 2005. During the interview Reynolds describes the change in the type of movies and why he chose to pursue a serious role as apposed to another comedic role. Reynolds describes how he tapped into playing the role of George Lutz and also different techniques used to help him into the role and the genre.
