 SPOILER: Originally, a "blood man" was brought in for the murder  sequence of Janet Fay. The "blood man" hooked up tubes to Janet  Fays body that would end at her head in which were connected to a  pump full of fake blood. Leonard Kastle (qv) said that "he wasnt  that good of a blood man", whereas the blood would go spurting out  in all directions, overall just doing it wrong. They ended up  purchasing condoms and filling them up with fake blood. They put the  condoms on top of Mary Jane Higby (qv)s head, with a tin plate  over it, with her night cap over that. They also put small nails in  the rubber hammer, so that it would pop the condoms upon impact.
