Paul Ferm, who played Santa Claus, is actually a former Miami area homicide detective. He actually made the child, Sean, played by Benny Weaver, cry during the "cage scene." Benny wouldn't return to the "cave" while Paul was present. Director Jason Hull had to cut a page from the script because Benny was so afraid of Paul.
All of the children on the maps were pictures given to the director by his friends. The 8 1/2 x 11's that are posted on either side of the map are actual missing children. The director and producers hoped it would be beneficial in helping to find the actual missing children.
