I am a fan. The first Stephen King novel I remember reading was Salem's Lot. I was terrified by it but couldn't put it down until the end. I don't usually go out of my way to read or watch movies that fit in the category of horror. Because Salem's Lot was so frightening for a long time I didn't read any of King's work.
Years later I rediscovered his work and loved what I found very much. I read the novels Misery and The Stand along with Delores Claiborn and Rose Madder. I found out that I could read Stephen King and still sleep at night. There is no denying that the man is a master storyteller and every chapter in any of them just made me want to keep going even in the 3 inch thick paperback of The Stand.
His collections of short stories were the books that I really enjoyed. The Shawshank Redemption which was a great movie came from the collection titled Different Seasons. The other collection I read was Skeleton Crew. This set of short stories includes The Mist by Stephen KingIt had another story that I remember which was Word Processor of the Gods. I don't know if I am strange but most of the time I like to read a book before seeing it in a film. The written work seems to help me put depth to the story on the screen and make it a better experience for me. If you like to do the same thing and read The Mist, Skeketon Crew was published in 1983, however I'll bet you can find it in a library or bookstore.
What I find exciting is that the same director that did The Shawshank Redemption also directed The Mist. To me that means a well crafted movie that I look forward to seeing even if it does scare me to death. If you want to know more than I can tell you here follow the links to the movie site. You can find trailers, downloads, a director's interview and more.
