Approximately 30 years ago, I watched a horror movie which I have been trying to identify for years. The problem is that after so many years I don't remember a lot about the movie and the only things I remember are blurred by time.
Here are the details that I do remember:
The movie was about a group of people staying in a house (I think they were a group of friends who gathered in the house, but this I cannot confirm).
There are some strange creatures (I remember them as a kind of small big-headed humanoids) which crawl out of the house's fireplace and attack the house inhabitants; in fact, I seem to remember that the creatures will wait for some person to be isolated from the others and then they will capture this person and drag him/her back to the fireplace, and kill him/her.
Does anyone know what movie this is?
