I think the movie you are talking about is "When a Stranger Calls."

I've never seen the original only this remake. The house design and Camilla Belle's looks are the only reason to own the movie. I thought it was kind of silly. In fact, it's funny that they even did this remake. The opening of the movie "Scream" is all about the girl in a house by herself who continues to pick up the telephone for a stranger.

Island Of Death

Not a horror film, but the original Straw Dogs (not the POS remake) is a pretty intense film.

I agree with STRAW DOGS, but I'm surprised no one has suggested Robert Wise's THE HAUNTING. It may have been made in 1963 and the dvd, if I recall correctly, is rated G, but it's still the scariest horror movie I've yet seen and certainly qualifies as being intense, at least in spots.

Yeah.
I was going to say The Strangers too.

The Strangers really let me down. I was hype for it, too. Loved the trailer.

This isn't very original, but I found The Exorcist (the legit, old timey 70s one) pretty intense. I don't know about all these other Exorcism movies lately; I haven't watched any.

The Spanish-language REC (the lame Jennifer Carpenter film, Quarantine, is a remake of it) had a degree of intensity, once it got going.

Also recommend The Loved Ones-hugely intense stuff

Oh, means...you have seen that shit?!:D
