Without financing the movie will never get made.
So you need to create a screenplay that someone will be willing to finance.
Finance of course begins with what the anticipated movie budget will be.
You help create the budget for your film by what you put into it,
and therefore have some ability to affect whether or not it can be financed.
A script that calls for tons of locations and characters is less likely to be made.
Did you know it's illegal for a movie to go over-budget?
Therefore a film must be shot within budget.
This means you as the writer have to compose a script that can be shot within budget.
So you can see how the budget is a really important aspect of your screenplay.
Exotic locations and luxurious expensive special effects will make your screenplay
not as marketable. Although it may be tempting to add cool but unnecessary extra locations,
special effects, stunts, scenes, actors, and props, doing so
lowers your chance of getting the script produced.
Practically speaking can your script be produced within a specific budget?
If not then it doesn't have much chance of getting financed.
If you simply keep budget in mind when choosing locations
you'll spend less time editing this later on. Think as if you are a financer,
wouldn't you be more willing to back a movie that requires a low budget? If the majority of scenes are shot in the studio that means less time shooting, a smaller budget, and larger profit. Locations can add up fast that's why it's important to keep this in mind at the beginning.
