inspired shower murder scene, was the bathroom  in Hamricks Brooklyn apartment. And a spooky stairway shown in the  film was in the same Tribeca building as his photography studio.  Hamrick and the films producer/star Joe Zaso (qv) became friends  when Hamrick shot some publicity stills (headshots) for Zaso. The  photographer is very familiar with the horror genre; he has written  several books about the cult classic "Dark Shadows".
