Three different hands were used as "undead Simon's" hand in the film; Kieran Valla (the actor), Ritchie Steven Filippi (the director), and Rob Vornkahl (the visual effects artist).
Shots had to be re-shot to preserve continuity when it was realized that a character can not stab someone with their left hand... when they don't have a left hand.
The writer and director met on-line via the Low Budget Horror Film Society Message Boards.
An old episode of ABC TV's 'One Life to Live', which actor Matthew Metzger stars in, is playing on the screen in the living room as Deke and Darcy watch TV. The episode (from 1996) features Ritchie Steven Filippi, the director (who is seen on screen).
