The film idea makes it reasonably easy to get POV right - I imagine the camera on my POV character's shoulder, close enough to pick up his thoughts. If I have to switch POV, the camera moves to someone else's shoulder.

I can't imagine never reading a book - though, these days, I have internet-concentration and my reading is much more broken up than it used to be. And it's weird, but apparently other people don't tell themselves stories. My son seems to be able to have a blank mind. When I'm in the car, although I'm concentrating on driving, there's usually a part of me busily thinking about something else. Boy, in the passenger seat, is thinking of nothing. Very odd.
