 Charleys old mobile home was located near the home of well known  Nevada artist Afton Frederick, who allowed the use of her home for  some exterior shots. Her husband Cliff Frederick helped the crew  with the night security of the old Varrick mobile home, because the  roof of Varricks home was fully removed for the ease of the camera  and lighting work inside. The weather was extremely warm during the  filming, which lasted seven weeks in the Dayton, Carson City, and  Genoa, Nevada area.
