I'm interested in seeing what people here think of a certain script-writing technique which I haven't seen employed very much but which did strike me as incredibly useful when I saw it used.
I hold that there are some things that you need to know a lot of details about the world as a writer that you don't need to ever tell anyone else, because it would bore the crap out of them. Whether you're like Tolkien and construct a whole new geography complete with maps, languages and a historical canon of literature to which you can actually refer accurately or you just happen to know what your protag's favourite food is even if he never visits a restaurant, you need to have a universe in your head in which all this plays out. With novels this is nice and self-contained, because you pick and choose which details out of your fantasy world you wish to convey specifically, which to infer, and which are just there to help you get the world to work in your head. However, when writing a stage or screen play, the audience isn't the audience, but the cast and director and producers and the various people whose job it is to convey this story to the real audience, the paying punters who are going to keep you in truffles and foie gras (or at the very least, in food and shelter). You tell them what to say and what to do, and then they have to expand on that in a thousand different ways, none of which it's really your job to describe.
However, there may still be some information which is important, but which does not fall into the category of what people are saying or doing at the time.
In Arthur Miller's The Crucible, he takes occasional time out from the play to present information which has nothing to do with the scene he is immediately describing, but instead to give detailed backstory on characters and situations. The world of The Crucible is one in which historic context and the specific relationships of the characters are important, but which would be incredibly clunky to get across in dialogue. So Miller says "hey, Cast, Director -- do your jobs." He gives them the information that they need to add background to their character, to understand "their motivations", and hence gives them the capacity to get that information across in the course of their acting or directing.
On to the relevance: the story I'm trying to tell takes place against a detailed, rich backdrop of political and religious intrigue which borrows from the real world but which is mostly all, y'know, made up. While it's not so important that the audience know the details it is pretty important that the characters know them. In a novel, I'd just write them, maybe drop some information in, but it's a film, so I'm going to be relying on actors and directors to know this backstory in order to properly understand just why this character doing this thing is important.
Would it be reasonable practice to break from the script, like Miller in The Crucible, and just tell people things? To not bother trying to insert them into the dialogue so that the actors can clunkily say those lines and themselves understand "Oh, OK, I am prejudiced against the French", but to come out and give them three or four paragraphs of "here's why you're prejudiced against the French, so you can get that across very subtly in ways that I would have been completely unable to get across if I'd just given you three lines of dialogue"? (random example, I have no plans to actually include any anti-French bias) It seems like a useful tool for a screenwriter to have, much in the same way that leaving comments all over your code helps other programmers come in and understand what you did, but as I said I haven't seen it used anywhere outside of Miller, and he wrote plays anyway. Is there some reason I should avoid doing this?
