I have avoided the movie because I really enjoyed the book, but I expect I will have to see it some day just because Tim Curry is a minor Sex God. (Not in ML's league mind you, just a minor).
The Green Mile was an outstanding movie, it's definately worth a look. I actually really enjoyed Pet Sematary (1), especially Fred Gwynne's character.
I have mixed feelings about a Dark Tower movie- I am nuts about the Dark Tower series and I can't think of any actor who could do Roland (or Jake, Eddie, Odetta....) justice. I think I want to leave my mental pictures of all of them my own, rather than "replacing" them in my minds eye with actors from the film. (Only a few months until the next Dark Tower book is released!!!)
