The point I was trying to communicate (And quite clearly some of it stayed in my head, sorry about that:)) was that I have a fondness for the 'architecture' of a story showing through if it's done right, be it Chekhov's Gun in Grey 17 is Missing or Breaking the Fourth Wall in Outbreak.
Yeah. When it's in your face, it's usually for a bit of comic relief.
Something I've been aware of but only recently discovered that there is a word for it, is
diegetic, and its complementary condition "extra-diegetic", in TV and film. I particularly enjoy when extra-diegetic sound track elements shift into the diegetic.
It's my favourite new word and I'll probably use it a lot for a while.

On a related note - I'm reminded of some discussion recounted on one of the LoTR special features DVDs, where a lighting director was trying to figure out the justification for placing a light in a certain position to highlight an actor's face, probably in Moria or some dark setting. He asks "where is the light coming from?", meaning "where in the context of the story's setting". Somebody else had then replied that it's from "the same place as the music!"
