Ok. For clarification:
In The Mouth Of Madness

Basically, he finally does go nuts. Know how it starts out with him in the asylum? He wasn't crazy then. He goes through and explains what happens to the guy who comes to see him, but remember when Sutter Kane tells him "I write therefore you are"? When he goes to see the film, he watches the film and it shows everything that happens during the movie....his brain just sort of goes the way of the dodo, because he realizes his entire life was nothing more than a piece of fiction. Got a very Lovecraft angle that, unless you've read a lot of Lovecraft, is hard to grasp.

One of my favorite films, right up there with Dr. Strangelove and Blade Runner.
