Good to hear that the movie is good.  Can't wait for it to come to DVD.  

I read the book long time ago.  It is by Stephen King.  I think it was one of the four novellas in one.  Yes, I remember "The Mist" being quite spellbinding.  I just love the way King writes about this almost claustrophobic situations where someone or something is out there waiting to get you.

But I remember the other story in the book, "The Langoliers" or was it "The Mangoliers" was more thrilling.  I think that was made into a TV movie.
