Gariepy was a minor character whose part expanded when Crawford (Joce) was unable to make several days of shooting. At one point, the main character, Crawford, doesn't appear for close to twenty minutes.
Warner's character was supposed to be a younger Father Edinger, but the actor was unable to film when needed so a new actor was brought in and character written. Edinger is still mentioned in the second story, however.
At any given point, certain actors were not available for shooting, so some scenes were shot with stand ins and edited together to look as though the two or three actors were.
There are many crosses and objects or scenery that resemble crosses in the film, including a character's name.
Production, since split into two films, shot over the course of a year and a half, beginning in spring of 2005, ending in fall of 2006.
