So I know a consultant who advises writers to use the title of the movie somewhere within the script. On one hand I think that sort of approach is too on the nose but on the other, I think she's on to something which made me think about how theme is expressed.
I've already admitted to being a big fan of The Title since it's the first marketing tool you have. Your title is the 70 point newspaper headline that draws people to your story. After that, comes another crucial element that, if absent, can make a script unsatisfying. Let's get all Freshman English and call it the lack of a "thesis sentence". In good scripts what the whole movie's about is often condensed in a few lines of character dialogue. It's where the writer says, "Hey guys, this is the idea I want to explore or have explored. Do you see how my story tests this idea?"
Why is this important? I think a good number of writers can execute plot, character, dialogue effectively, but nailing story to a theme represents a level of sophistication that sometimes eludes even the more experienced writer. I used to read several entertaining scripts for a couple production companies but at the end of the day, the scripts didn't stick with you because they didn't have a thematic point. The writer didn't hand you the lens you needed to view the story events through. I think when execs or producers talk about a story staying with them, they're really talking about how the theme resonates and the best way to achieve that resonance is through title and "thesis sentence."
There are no rules about where the dialogue that explains the heart of the movie has to fall. In the three examples below, one comes at the beginning, one at the climax and one at the end as a sort of "moral of the story."
One of the simplest execution of "thesis sentence" ever must be Richard Curtis' "Love Actually". It's probably so bare because Curtis knows he has to give the reader of the multi-stranded narrative something to hold on to before he delves into the eight story lines(!) we'll be weaving in and out of. The prologue says: this writer has a plan. It is all, at the end of the day, going to mean something.
Here's the opening voice over....

PRIME MINISTER
Whenever I get gloomy about the state of the world, I think about the arrivals gate at Heathrow airport. General opinion has started to make out that we live in a world of hatred and greed but I don't see that(... )If you look for it, I've got a sneaky feeling you'll find that love is actually all around.

And we're into the movie and able to enjoy it and take meaning from it because of the "thesis sentence." (I prefer thesis sentence to theme because it's more specific. Theme makes me think of generalities like "love is everywhere" but the thesis sentence gives you a more precise road map...Curtis tells you, this is a modern, Britain in post 9/11 story and these are the specific types of love I'll be dealing with in my argument.) The opening helps a reader relax, know what to look for and settle in for the read.
The thesis sentence doesn't always have to be so obvious but it should somehow tie in to the title. Here's an example from 2008's The Visitor, a personal favorite of mine...not much of a surprise given its subject matter. In this scene, the mother of an undocumented immigrant is confessing her culpability in his detention.

MOUNA
It's my fault. What happened to Tarek. I did receive the letter telling us to leave. I threw it away. I never told him. We were here for three years by the time the letter arrived. I had found a job. Tarek was in school. Everyone told me not to worry. That the government did not care. And it appeared to be true. And then, after a time, you forget. You think that you really belong.
[/scrippet]
Again here's the thesis sentence that screenwriter Tom McCarthy's been holding back until the climax of the movie. He wants to explore the question of belonging and of course ties it into the movie's title: The Visitor. (I think McCarthy wants us to question who "the visitor" is...Is it Tarek, the undocumented immigrant or is it Walter Vale, the shut-down professor who's coming alive by being introduced to a world he didn't know existed.) That's the movie boiled down to a couple sentences.
But my all time favorite thesis sentence comes from another movie about outsiders "Dirty Pretty Things." At the climax where protagonist Okwe has duped his employer and is delivering contraband to a white buyer, the buyer asks... "How come I've never seen you before?"
And here's Okwe's response which puts an exclamation mark on the idea of invisibility that writer Steven Knight has been touching on throughout.

OKWE
We are the people you do not see. We are the ones who drive your cabs. We clean your rooms and suck your cocks.
[/scrippet]
...to which Juliette, his hooker pal, (beautifully played by Sophie Okonedo in the movie) raises her hand to say yeah, I'm present.
It is a powerful iteration of theme and it comes at the climax of the movie. It also ties into the title "Dirty Pretty Things": we get our hands dirty to make your life pretty. (Some day I will get into how Miramax's marketing of this movie and its giving the title an intentionally misleading spin still galls me.)
So does your script have a thesis sentence? Doesn't have to... but a couple lines of dialogue can give the reader an unmistakable lens through which to view your story.
