The Voodoo Factor

I was eight years old when this was first shown and although young loved anything a little different and scary. This well and truly fitted the bill. Luckily my parents let me watch this programme and in particular I remember the "goddess" laying with all the spiders over her and the darkened outline of the "spider statue" which I believe contained jewels, scared me. Another part which is a bit hazy was of a couple in a room and one leaning against a door from which what I can only describe and tentacles came over the door and proceeded to go around the persons neck! For its time it was very good - the same era as A for Andromeda which also stays in my mind. Are there still copies around that can be purchased?
