How to Use Parentheticals in a Screenplay

A parenthetical is a short, lowercase instruction in parentheses between the character cue and the speech: (beat), (quiet), (to Jake). It's indented to ~3.1" and kept under about two inches wide — a narrow doorway between the name and the line, meant to be used rarely.

The Format

                         MARA
                (to the waiter)
          He'll have the eggs.

                         WAITER
                (unnerved)
          We stop serving at eleven.

                         MARA
                (beat)
          It's 10:58.

• Lowercase, in parentheses, on its own line under the cue
• Indented ~3.1" from the page edge, between the cue column and the dialogue column (margins)
• Short — one to four words

The Three Legitimate Uses

1. Address — who the line is aimed at

                (to Jake)
                (into the radio)
                (to herself)

Useful in group scenes where the target of a line would otherwise be ambiguous.

2. Attitude — the emotional subtext that changes the line's meaning

                (quiet)
                (delighted)
                (lying)

The test: would the line be misread without it? If two different deliveries produce two different meanings, and only one is right, earn a parenthetical.

3. Rhythm — the beat

(beat) is the most-used parenthetical in screenwriting: a pause, a gear-change, a moment of thought. (then) is its sibling — the delayed reaction. These are legitimate and common; just don't let every speech take a beat before starting.

What Parentheticals Are Not

Not acting directions. This is the classic amateur tell:

                         MARA
          (sighing, glancing at her watch,
          then smiling tightly as she
          stands)
          We should go.

If the behavior matters, it belongs in an action line — where the actor, director, and reader all get it. Parentheticals direct the line, never the performance.

Not mini-action blocks. Anything physical (standing, crossing to the window, lighting a cigarette) goes below as action.

Not emotional narration. (angry that her father never called) is backstory, not staging.

Parentheticals vs. Extensions

(V.O.), (O.S.), (CONT'D) look like parentheticals but are extensions — they attach to the character cue and describe where/how the speech happens, not how to deliver it:

                         NARRATOR (V.O.)
          The bridge froze before the rain
          did.

A Useful Ratio

Professional scripts average roughly one parenthetical per 3–5 pages. If you're writing one per page:

1. Your dialogue may be doing the emotional work of action (or avoiding it)
2. You may not trust the actors — unnecessarily
3. Convert physical parentheticals into action lines and keep only true attitude cues

Frequently Asked Questions

Is (beat) a parenthetical?

Yes — the most accepted one. It marks a pause in the speech's rhythm.

Are parentheticals capitalized?

No — lowercase, inside parentheses, on their own line between cue and dialogue.

Can a parenthetical come after the dialogue starts?

Conventionally no. Some writers place (beat) mid-speech on rare occasions; if you need it more than once, break the speech with an action line instead.

What's the difference between a parenthetical and an extension?

Extensions ((V.O.), (CONT'D)) attach to the cue and describe the situation of the speech; parentheticals describe its delivery.
