You can do everything differently in a novel. Hero narrates the novel; we're in his head. You're hearing all his thought processes and you're hearing him call himself out on his bad behavior. You don't have the benefit of that narrator in a movie. What you see a character do, very often, becomes that much more important because you don't have him editorializing it for you.
When the reader and one narrator know something the other narrator does not, the opportunities for suspense and plot development and the shifting of reader sympathies get really interesting.
And it [Fight Club novel] was written so general that my father thought I was writing about his father, and my boss thought I was writing about his boss. People really put themselves, you know, in the shoes of the narrator.
I've always felt that the traditional novel doesn't give you enough information about the narrator, and I think it's important to know the point of view from which these tales are told: the moral makeup of the teller.
I'm not first and foremost interested in story and the what-happens, but I'm interested in who's telling it and how they're telling it and the effects of whatever happened on the characters and the people.
My preferred style is to write in first person, so I always have to play around with possible narrator voices until I find something that works.
When someone walks in and you say "a six-foot-tall man," you miss the opportunity to describe what a six-foot-tall man would look like to your narrator, because how the narrator describes a six-foot-tall man says more about the narrator than about the man.
I almost always use first person voice in my novels. It has its limitations, but it gives a sense of immediacy that's hard to create with an anonymous, all-seeing narrator.
I can't reasonably pretend to be a transparent and omniscient narrator who brings no personal perspective. That person doesn't exist.
