A promising screenplay idea is not always a complete story. Before you spend months drafting, use these five practical questions to test the concept, uncover gaps and decide what needs developing first.
There is a lovely little stage at the beginning of a new screenplay where everything seems possible.
You have an idea. Perhaps you can already see the opening scene. You know who the main character is. There is a terrific twist lurking somewhere near the end. Maybe you have even heard a few lines of dialogue in your head.
And because those pieces feel so vivid, it’s easy to think: Yep. There’s a screenplay in this.So you open a new document and start writing.
Then, somewhere around page 25, 40 or 60, things become considerably less lovely.
The middle starts sagging. Your character seems to be wandering around waiting for something interesting to happen. The ending you thought would sort itself out stubbornly refuses to do so. Or you discover that the brilliant premise you loved can really only sustain about twenty minutes of story.
This does not necessarily mean you cannot write. It may simply mean you started writing the screenplay before you had tested the idea.
A Good Idea Is Not Automatically a Whole Story
Most screenplay ideas do not arrive neatly packaged with a beginning, middle, end, character arc, escalating conflict and satisfying resolution. Usually we get a fragment. It might be:
- an unusual situation
- an interesting character
- an arresting image
- a clever twist
- a relationship
- a setting
- a piece of dialogue
- a moral dilemma
- an emotional question
That fragment can be excellent. But it is still a fragment.
Screen Australia makes a similar distinction in its guidance on story development. Its Story Documents – Drama resource notes that an idea on its own does not necessarily provide the foundations for a viable production. It recommends identifying and testing the core concept while the project is still developing, rather than assuming repeated drafting will repair a weak foundation.
That does not mean every writer needs to produce an enormous outline before writing page one, far from it. Some writers plan extensively. Others discover much more of the story through drafting. But even if you are firmly in the discovery-writing camp, there are a few things worth knowing before you commit months to a screenplay.
Think of it less as planning the whole journey and more as checking that there is actually a road.
What Does It Mean to Test a Screenplay Idea?
You are not trying to prove that your idea is brilliant. You are not trying to predict whether anyone will buy it. And you certainly are not trying to eliminate every uncertainty before you begin. You are simply asking whether there is enough dramatic material in the idea to justify developing it further.
Screen Australia’s development material puts considerable emphasis on the underlying core concept, including the dramatic problem, what the characters are compelled to do and the consequences of failure.
So before you start drafting, give your idea a quick pressure test. Here are five questions I would ask.
1. Can You Explain the Story Clearly?
Try explaining your screenplay in one or two sentences.
Not every subplot. Not the backstory of six supporting characters. Just the heart of it.
Who is this about?
What happens?
What does that person have to do?
What makes that difficult?
And why does it matter?
For example: After inheriting her estranged father’s failing country pub, a city accountant must keep it running for three months to claim the property, forcing her to confront the community and family history she spent years avoiding.
It is not a finished pitch. It probably is not even a finished story. But we can already see a person, a situation, a problem and some pressure.
Compare that with: A woman inherits a pub and learns a lot about herself and the people who live in the town.
There may still be a wonderful screenplay hiding inside that second version. But right now, I would want to dig further.
What does she actually have to do?
Why can’t she simply sell the pub?
What is stopping her?
What happens if she fails?
Struggling to explain an idea does not automatically mean the idea is bad. Sometimes it simply reveals the part you have not worked out yet.
That’s exactly why this exercise is useful.
2. Does Your Main Character Want Something Specific?
Characters can want all sorts of things emotionally. They might want:
- acceptance
- love
- freedom
- forgiveness
- belonging
- confidence
- a fresh start
Those things matter. But for a screenplay, it also helps if there is something we can actually watch the character pursue. Maybe they need to:
- win the court case
- find the missing child
- save the family business
- get elected
- escape the town
- reconcile with their daughter
- expose a fraud
- survive until morning
That external objective gives the story somewhere to go. Then the deeper emotional need can sit underneath it.
Ask yourself: What is my character trying to achieve during this story?
Then ask: What happens if they do not achieve it? Those consequences create stakes.
Screen Australia’s guidance on loglines describes the dramatic heart of a story in very practical terms: something happens, someone is compelled to act, and there are consequences if they fail.
You do not need to force your screenplay into a formula. But if your protagonist could simply decide not to bother and nothing much would change, you may need to strengthen the dramatic engine.
3. Can the Idea Keep Creating Problems?
One obstacle is rarely enough for a feature-length screenplay. Your premise needs the ability to generate more story.
Suppose your screenplay is about a woman trying to save her family’s bookshop. Great.
Her landlord increases the rent. There is your first problem. But what happens next? Perhaps:
- her biggest supplier cuts her credit
- her brother wants to sell the business
- an online competitor opens a warehouse nearby
- she discovers the shop has debts she did not know about
- the publicity stunt she organises goes badly wrong
- saving the business forces her to sacrifice something else she values
Notice that these are not five random unfortunate events dropped on top of the character.
Ideally, each complication grows from the situation and forces another decision. That is where conflict becomes useful. It is not simply bad things happening. It is pressure producing choices. And choices producing consequences.
Try writing down five complications your premise could naturally generate. If you can think of fifteen, terrific. If you cannot get past one, do not panic. It simply tells you that the premise may need more development before you commit to the full script.
4. Can You See Where the Story Might Land?
You do not have to know the exact ending. I am not going to confiscate your keyboard if you have not decided whether the final scene happens at sunrise or in a Woolworths car park. But I do think it helps to know the direction of travel.
What will be different by the end? Will the character:
- succeed?
- fail?
- get what they wanted but discover it was not what they needed?
- make a decision they could not have made at the beginning?
- expose something?
- surrender something?
- repair something?
- finally walk away?
You can change your mind later. Writers do. The point is not to lock yourself into an ending before you have earned it, but rather to check whether the premise is actually moving towards something.
If you genuinely have no idea how the central problem could ever resolve, spend a little more time with the idea. Sometimes the ending is not the problem. Sometimes an uncertain ending shows you that the beginning hasn’t asked a strong enough question.
5. Is This Actually a Screen Story?
This one matters.
A screenplay is not simply a novel with fewer words. Film and television communicate predominantly through what an audience can see and hear. That means an idea that depends heavily on explanation, internal thought or pages of reflection may need to be reconceived before it works effectively on screen.
Ask yourself: What would we actually watch?
Suppose the central idea is: A retired teacher gradually realises she regrets the choices she made thirty years earlier. Interesting. But what happens on screen?
Perhaps an old friend returns.
Perhaps a box of letters is discovered.
Perhaps she travels somewhere she has avoided for decades.
Perhaps someone from that earlier life asks her to do something now.
Suddenly we have behaviour, decisions, relationships and consequences that an audience can experience. The internal story has found an external form.
That is the shift you are looking for.
Screen Australia’s current short-film assessment criteria, for example, consider not only whether a story is strong and distinctive, but whether it suits the film form and is ready to be produced.
Your early idea does not need to be production-ready. But it does need the potential to become something we can watch.
Give Your Idea the One-Hour Test
You can do all of this without producing a forty-page treatment.
Give yourself an hour and write:
1. Your story in two sentences:Who is it about, what happens and what must they do?
2. Your protagonist’s goal:What are they actively trying to achieve?
3. The stakes:What changes if they fail?
4. Five complications:What can naturally make their objective harder?
5. The likely ending:You only need a direction.
6. Three scenes you can already see:What would an audience actually watch or hear?
Then stop and read what you have written.
You are not looking for perfection. You are looking for story energy.
Does one answer naturally lead to another? Do complications keep appearing? Does the character have decisions to make? Can you imagine scenes rather than explanations? Does thinking about the ending reveal something interesting about the beginning?
If so, you probably have something worth developing.
If the Idea Doesn’t Pass?
Excellent.
Seriously.
You have just learned something useful before writing 90 pages.
Perhaps your protagonist needs a clearer objective. Perhaps the stakes are too low. Perhaps the brilliant twist is actually the whole idea, and you still need a story around it. Perhaps there is not enough conflict yet. Perhaps the premise would make a cracking short film rather than a feature. Perhaps the idea belongs in a novel instead. Or perhaps one missing piece will suddenly make everything else click.
This is development. It is not failure.
Queensland Writers Centre currently runs both its Pitchable program, which starts with an idea or concept, and its Scriptable program for developing screenplays. Those separate stages remind us that developing an idea and writing a finished script are not the same task.
There is no prize for discovering the central problem with your screenplay after six months instead of before you begin.
Don’t Test the Life Out of It
The other extreme is also dangerous. Some writers become so determined to solve every possible problem before drafting that the screenplay never gets written.
That is not what I am suggesting. You do not need:
- every scene
- every beat
- every character detail
- every line of research
- every subplot
- the perfect ending
before you begin. The test is merely there to answer: Is there enough here to explore? Once the answer is yes, write.
You will discover things in the drafting. Characters will surprise you. Scenes will change. The ending may move. A subplot you thought was essential may disappear completely.
That is part of writing.
Planning should support the work, not replace it.
The Real Value of Testing Your Idea
Testing a screenplay idea is not about deciding whether you are talented enough to write it. It is not even about deciding whether the idea is objectively “good”. But rather, you are trying to see the idea clearly enough to understand what it currently has and what it still needs.
That is a much more useful question.
A concept that feels weak today may become terrific after you identify the missing source of conflict. A complicated premise may become much stronger when you strip away three things. A character who seems passive may come alive the moment you give them something specific to fight for. And occasionally, you will discover that the idea you were about to spend months writing simply is not ready yet. That is useful too.
Because the goal is not to avoid the work. It is to make sure the idea has enough underneath it to carry the work.
Then you can open that blank screenplay document with considerably more than enthusiasm.
You have somewhere to go.
