An Interesting Exercise

I'm trying to come up with a good what-if scenario for this question. Let's try it this way --

Suppose you find yourself stuck in a parallel universe, where they have movies, but not the same ones we do.

You have a chance to pitch a movie you want to write to a parallel universe studio head, and you realize that you have the entire history of our world's movies to draw on.

Setting aside the dicey moral question of rewriting (or copying) someone's work from this world to present in this parallel world, what story would you choose?

Or, rephrased, what movie that has ever been made seems to be the one that you'd choose to get someone (who is unfamiliar with all movies) to instantly want you to write it?

What movie has the perfect hook, the wanna-see factor, the perfect representation of all things that everyone is currently looking for in a movie?

I think it's an interesting question, because it really goes to the heart of the issue of the kinds of things people should write if they really want to break into the business in a big way.

So now you're in parallel-world-land, you have a meeting with me, and you need to pitch something. The fate of Earth is at stake (somehow, just to up the ante. Ticking clock). What do you pitch?

Go.
