THE STORY VAULT BLOG
It dismays me when writers compare writing a screenplay to building a house. Typically, the argument goes “you build a foundation and only then you fill everything in because you wouldn’t build a house without a foundation.” It sounds sensible. But is it?
If the foundation is structure, then what are characters? Dialogue? Pacing? Setups and payoffs? Rewatch value? Are those just countertops and light fixtures, merely decorative elements selected after the “real” work is done?
The weakness of the analogy becomes apparent the moment it's examined.
The biggest danger of the “screenplay as a house” analogy is that it creates confusion by conflating foundation and structure. The foundation of a house and the foundation of a screenplay are not the same thing. The foundation of a house is physical: the foundation of a screenplay is conceptual.
A building can be structurally sound and still be uninhabitable. In the same way, a screenplay can hit every prescribed beat and still feel hollow. Structure alone does not create meaning. It is the frame that holds meaning.
Structurally sound, but would you want to inhabit it?
The premise of this post is as follows: The foundation of a screenplay is not its structure. The foundation of a screenplay is its central idea. The central idea being the core dramatic argument everything rests upon.
A screenplay is conceptual, not physical. You do not experience a film the way you experience a building. You can walk around a house, inspect it from outside and walk around any room. With a work of fiction, you move through it moment by moment.
To put it simply: structure is the arrangement of events over time.
When you read a screenplay you are not travelling through a physical space. You are travelling through time. Screenplay structure is “events occurring within a given space of time.” And your foundation is the central idea expressed through events that occur over time.
Consider Casablanca. Pages were being written on set, daily. The actors were unsure of how to play their parts because they didn’t know how the story would end. Obviously, this is not a practical approach to making a movie, but it illustrates something important: the film did not collapse because every beat hadn’t been predetermined.
Rick expresses the central idea in the movie’s final scene:
“Ilsa, I'm no good at being noble, but it doesn't take much to see that the problems of three little people don't amount to a hill of beans in this crazy world.“
That is the foundation. The idea that there are causes greater than individual desires. Every major turn in the story reinforces that idea. The structure serves this foundational idea. The film is successful because the writers and the director knew the foundation of the story was an idea...and they remained true to it.
Of course structure is important. But structure is the framework that carries the story forward in time. It is not what the story is built upon. Story structure is not a physical thing anymore than the central idea is a physical thing. Applying a physical analogy to storytelling is self-limiting because it doesn’t fit.
The foundation of a screenplay is the dramatic idea: the thematic argument expressed through unfolding events.
It’s not a roof or a floor plan or a series of plot points. It’s an idea. You can determine the conclusion before you know the midpoint. You can create your antagonist before you imagine the inciting incident. You can do anything in any order so long as you know the foundation of your story - the central idea - and you consistently carry it through from beginning to end. All of the elements can be woven together so long as you are true to your foundational idea.
None of this is to say you can't or shouldn't create a beat sheet or structure your story in advance of creating characters, dialogue, and conflict and resolution. But it isn't absolutely necessary. Whatever your approach, if you don't understand that the true foundation of a story is its central idea then it will be difficult to sustain your story from beginning to end in a manner that will resonate with an audience.
