Paul Michael Glaser is one of Arnold Schwarzenegger's best movies, filled with wild action and terrific one-liners, but any Stephen King fan will tell you that it bares almost zero resemblance to its source material. The same character names pop up in both the film and the book, and they are both works of dystopian fiction, but they are otherwise two very different approaches to the central conceit.
One person who is very aware of these differences is writer/director Edgar Wright, and it's apparently a big thing driving him in the creation of the remake he currently has in the works.
