I've been stratching my head for days now over this sodding film!
I must have been about 7 when the film as rented from the old video store, so the film could be from the 80's - 90's.
The general plot from what I can vaguely recall was that a few people enter a mansion, for what reason I cannot remember, and are basically terrorised by a clown doll / jester type thing! The scene that I remember most vividly was one of the people died via means of the floor opening up and being burned alive in some sort of acid - that looked like milk!
My memory isn't what it used to be but I am sure there is a monkey toy with clapping cymbals involved, and a barking dog (perhaps)!
The closest I could find to the film by googling etc was this UNANSWERED post here:
Thanks in advance!
