For a "b" movie Roger Corman production,, this wasn't that bad at all really.. sure could have been better, but given the budget, and the time period that it was made I thought it was delightful.. sort of a poor man's House on the Haunted Hill if you will,, 4 people have to spend time in a house in order to qualify for the reading of the will of their father,, whom of course they all hated. very creepy house,, lot's of misdoings going on there,, and sure enough slowly 1 by 1 people start disappearing and dying left and right. all we have to do now is figure out who in the world done it,, was it the butler.. ala Clue,, or was it someone else,, watch and find out.
