Frame One

Screenplay dialogue is not real speech. It is a shaped version of it, written so that every line does work: it reveals a character, moves the story or sharpens a conflict. The method starts with the character, not the line: have the person clearly in mind, know what they want, let them push against each other, then read the scene aloud and cut.

This guide takes those steps in order and ends with a checklist.

1. Dialogue is not real speech

Record a real conversation and write it down word for word, and it is almost unreadable: filler, repetition, trailing thoughts, small talk. Screen dialogue keeps the rhythm of speech and drops most of the rest. Celtx’s guide to realistic dialogue describes it as life with the uninteresting parts cut out.

Element	Real speech	Screen dialogue
Filler words	Constant	Used sparingly, and only when they say something about the character
Small talk	Common	Cut unless it creates tension or avoids a subject
Sentences	Often long and rambling	Short, with fragments and contractions
Interruptions	Frequent	Kept where they show pressure or power

2. Start from the character, not from yourself

The most common source of weak dialogue is the writer. A line that sounds clever or true to the writer is not necessarily a line the character would say. When that happens, every character ends up sounding like the writer.

The fix is to have the character clearly in mind before writing a single line. The question is never what sounds good, or what you would say in that situation. The question is what this person would say here, and how they would say it. A line the writer loves but the character would never say has to go, however good it is.

Five questions help to pin the character down:

1. Who is this person? Age, work, background.
2. What do they want in this scene?
3. How do they speak? Short or long sentences, formal or blunt, which words they use.
4. How do they speak when they are nervous?
5. What would they never say out loud?

The scene in the next section is built from these answers.

3. Know what each character wants

A line of dialogue is an action: one character does something to another by speaking. Before writing a scene, decide what each character wants from the other, and what they do to get it. StudioBinder suggests writing the dialogue last, once the wants are clear.

In acting terms, the want is the objective and the method is the tactic. For how this reads on the page, see How Actors Build a Character From the Page Alone.

Here are the answers to the five questions for two characters, followed by the scene they produce.

• CAROL, 58, school bus driver. She wants her son to say it himself. She speaks in short statements. When she means something else, she asks about logistics. She never names a feeling.
• DANIEL, 26, junior accountant. He wants her blessing without a fight. When he is nervous he talks like his workplace: full sentences, words like “opportunity” and “transparent.”

INT. CAROL'S KITCHEN - EVENING

CAROL (58) sits at the table sewing a button onto a winter
coat. DANIEL (26, office jacket) stands in the doorway with
his shoes still on.

                    DANIEL
          Mom, I wanted to be transparent with you
          about something.

                    CAROL
          Your shoes are on.

He takes them off by the door and sits.

                    DANIEL
          There's an opportunity at work. A role in
          the Lisbon office. It's a significant step,
          and I wanted you to hear it from me.

                    CAROL
          Is it a contract or permanent?

                    DANIEL
          Permanent. Mom, I haven't made a decision yet.

                    CAROL
          There was a letter from a relocation company
          on the hall table. It had your name on it.

He looks at the coat.

                    DANIEL
          I was going to tell you this weekend.

                    CAROL
          It came last Friday.

She bites the thread. Holds the coat up to the light.

                    CAROL
          Is it cold there?

                    DANIEL
          It's Lisbon. It's mild.

                    CAROL
          Mild is still wet. Take this one.

                    DANIEL
          I'll buy a coat there.

                    CAROL
          They pay at the end of the month.

                    DANIEL
          They're covering the first month. It's part
          of the package.

                    CAROL
          Then buy one with their money. Take this
          one anyway.

He takes the coat. She snaps the lid on the sewing tin.

                    CAROL
          Who has the key to your apartment?

                    DANIEL
          Mom.

                    CAROL
          Somebody should have it.

What the lines show

• Daniel’s first line. “Transparent,” “opportunity” and “significant step” are his workplace voice. He reaches for it because he is afraid of this conversation.
• “Your shoes are on.” Carol takes control of the room before the conversation begins.
• “Is it a contract or permanent?” She never asks whether he is leaving. She asks about the contract, the weather, the money and the key. Logistics are how she says it.
• “It came last Friday.” She has known for days and waited. It is a fact, not a feeling, and it carries more weight than any complaint.
• The coat. Her action carries what she cannot say. She is giving him something to take with him.
• What is missing. Neither says “I’ll miss you” or “I’m afraid.” Each speaks the way they would, and the audience fills in the rest.

4. Let characters listen and push back

Each line should respond to what was just said, not to what the writer needs said next. Characters in conflict rarely answer the question asked. They deflect, answer a different question or ask one back. A reply in the form of a question forces the other character to justify themselves, and it is one of the simplest ways to build pressure.

Long stretches of agreement leave little to watch. When two characters want different things, the dialogue produces its own tension.

5. Give each character a distinct voice

Cover the character names in a scene. If you cannot tell who is speaking, the voices are too alike. This is a test you can run on any page.

Voices differ in vocabulary, sentence length, rhythm and what a character avoids saying. A tense character may speak in short, blunt lines, and a persuader in longer, winding ones.

Accents and dialects are best suggested through word choice, grammar and idiom, not through phonetic spelling. Script Magazine points out that phonetic spelling is laborious to read, and a screenplay is read before it is produced.

6. Keep it short and let the page breathe

Celtx’s formatting guide suggests keeping each dialogue block under about four lines. A longer speech can be broken up with an action line or another character’s reaction. An interruption is marked with a dash at the point where it happens, and a trailing thought with an ellipsis. The layout rules are in How to Format a Screenplay.

A silence, a look or an action can replace a line. When the story can be told without words, the version without words is often stronger.

7. Say less

Characters who state their feelings or explain the plot leave the audience nothing to work out. The two common failures are covered separately: subtext in Text, Context and Subtext in Screenwriting Explained, and exposition in 7 Things Beginners Put in a Screenplay That Don’t Belong.

A quick check: if a line states a feeling directly, ask what the character would do or say instead to hide it.

8. Read it aloud and cut

Lines that look right on the page can sound clumsy when spoken. Read the scene aloud, or ask someone else to read it, and mark every place where the reading stumbles. Then cut. Greetings and small talk go first, along with any line that repeats what the previous line already said.

A seven-question checklist

1. Would this character say this, in this way?
2. Does each character want something in this scene?
3. Does each line respond to the one before it?
4. Can I tell who is speaking with the names covered?
5. Would a person say this out loud?
6. Does any line state something the audience already knows or can see?
7. What can I cut?

Frequently asked questions

Whose voice should the dialogue be in?
The character’s. A line that sounds clever to the writer but does not belong to the character should be cut, even when it is good.

How long should a line of dialogue be?
Short lines read better, and a block of about four lines or fewer is a common guide. Break a longer speech with action or a reaction.

Should I write dialogue the way people really talk?
Not exactly. Keep the rhythm, the fragments and the contractions, and cut most of the filler and small talk.

How do I make my characters sound different?
Vary vocabulary, sentence length and rhythm, and test it by covering the names.

How do I write an accent?
Suggest it through word choice, grammar and idiom. Phonetic spelling slows the reader.

Should dialogue explain the plot?
No. When a character needs the information, a line can deliver it. When only the audience needs it, find another way.
