How to Format Dual Dialogue in a Screenplay

Dual dialogue is two characters delivering lines simultaneously, rendered as two dialogue blocks side by side on the page. It's a rare, deliberate device: arguments that talk past each other, oaths spoken in unison, two people on the phone at once.

The Format

In a PDF, dual dialogue places two complete cue + speech columns next to each other:

           MARA                    JAKE
    I never said           You said it the
    that.                  night you left.

    I never--              Don't.

Structure rules:

• Both blocks keep the standard cue/parenthetical/speech structure, compressed side by side
• Keep simultaneous lines short — the columns are narrow; more than ~6 words per line becomes unreadable
• The reader reads left block, then right block, then down — write so the exchange works in that order

When Dual Dialogue Works

Overlapping argument

           MARA                    JAKE
    Because you             I am not doing
    always do this!         this again!

Unison / ritual

           CROWD                    PRIEST
    ...deliver us from       ...deliver us
    evil...                  from evil...

Cross-cut phone banter

Two callers talking over each other just before the INTERCUT kicks in (phone calls).

When to Avoid It

• Information-carrying lines — if the audience needs both lines fully, they can't process them simultaneously; sequence them instead
• Long speeches — dual dialogue with more than 2–3 exchanges is exhausting to read and play
• As decoration — simultaneous talking that isn't dramatically motivated reads as a gimmick

If the moment is really about interruption, sequential lines with -- (interruption format) almost always land harder than true simultaneity.

Dual Dialogue in Fountain

Fountain has no native dual-dialogue syntax; apps use the ^ convention — a caret on its own line marks dialogue that belongs side-by-side with the previous block (see Fountain Syntax):

MARA
I never said that.

JAKE
^You said it the night you left.

Screenplay software (Final Draft, Scripta, Fade In) has a dedicated dual-dialogue command that handles layout and pagination.

Frequently Asked Questions

How do I write dual dialogue in Final Draft?

Select the two dialogue blocks and use Format → Dual Dialogue (menu name varies by version). Scripta and Fade In have equivalent one-click commands.

Can dual dialogue include parentheticals?

Yes, but it's cramped. Keep parentheticals out of dual columns where possible.

How often should I use dual dialogue?

Sparingly — a handful of times in a feature at most. Its power comes from rarity.

Does dual dialogue count as one or two speeches?

Two — each block has its own cue, and each character is separately credited and counted.
