 The production team had many ideas for casting, and Richard Hatem says that Skeet Ulrich was one of the first ideas for an actor to play Paul Callan.However, the producers believed that Ulrich was "unavailable", and that he was taking a break from acting and living with his wife and kids in Virginia.Among the other actors who auditioned for Paul Callan were Matthew Fox, known for his starring role on the series "Party of Five" and who went on to star in "Lost", and Jason Priestley, which Hatem says "would have been an excellent casting pun".
