Dialogue Formatting
When to use parentheticals, voice-over, off-screen speech, dual dialogue and intercuts—and when to leave them alone.
01 / The idea
When should screenplay dialogue use special formatting?
Only when the reader needs information that ordinary character cue plus dialogue cannot supply. Special notation should clarify sound source or simultaneity, not decorate the exchange.
Formatting is meant to help the reader forget they are reading. Once the basics are right, the page gets out of the way and the film can start playing in their head.
02 / What to remember
Three things worth holding onto
None of this is about looking clever or perfectly ‘industry’. It's about being considerate to the next person who opens the PDF and giving your story the cleanest possible read.
Parentheticals are surgical
Use them for a necessary contradiction, addressee or playable clarification that context cannot provide—not to direct every line reading.
Extensions describe sound source
V.O. usually means narration or speech from another time or space; O.S. means the speaker is present in the scene but outside the frame.
Intercuts simplify repeated locations
Once both sides of a call are established, an INTERCUT can avoid a forest of alternating scene headings.
03 / On the page
Try it this way
Set things up once, keep the process simple and save your attention for the writing. The best workflow is usually the one you can still trust at eleven o'clock the night before a deadline.
- 1
Format the simple version first
Most dialogue needs only a character cue and the spoken line.
- 2
Add notation for a reader problem
Use an extension or parenthetical when ambiguity would otherwise change the scene.
- 3
Test dual dialogue carefully
Reserve side-by-side speech for genuinely simultaneous lines; software should handle the layout.
- 4
Inspect the page
Special formatting should make the exchange easier to scan, not denser.
04 / Trouble spots
If this feels familiar, take another look
V.O. and O.S. are used interchangeably.
Parentheticals carry full actions or emotional essays.
Every overlap is formatted as dual dialogue.
Character cue spelling changes across scenes.
Don't treat this list as a scorecard. Every draft has a few of these. Pick the one causing the most trouble, find the earliest place it appears and work forward from there.
05 / Have a go
Try this on your script
Format the same phone conversation three ways: hearing one side, cutting between both locations and using an intercut. Choose based on dramatic focus, not novelty.
