Haven't read Misery yet, but I agree the movie is amazing.
Well if I remember correctly, there has been talk about either a new movie, or a new mini-series of The Tommyknockers. This is one I haven't yet seen, or read yet. All I know of it is from The Nostalgia Critic's review of it from a few years ago.
I agree hopefully it won't get remade, but I wouldn't rule it out. Hollywood just loves remaking things that don't need it. They also seem to want to make sequels to movies that don't need one, and ignore the ones that do.
