Nora Ephron’s approach to dialogue

Nora Ephron created a distinctive approach to dialogue, one studied in screenwriting programs. Analyzing how her dialogue works is among the film’s most valuable lessons.

The principal techniques

1. Dialogue as an arena of conflict

Nearly every conversation in this film is a micro-conflict. Harry and Sally do not speak simply to exchange information. They speak to win. Each defends a worldview, and their verbal clash generates narrative energy. The technique lies in giving every character a strong opinion and putting them at odds over everything, even the small things.

2. Wit as characterization

Harry uses irony as armor. Sally uses precision as control. How they speak says more than what they say. Ephron gives each character a distinctive voice in dialogue. Harry tends to generalize—“every man...,” “no woman...” —while Sally tends to qualify—“not EVERYONE, only....” The contrast makes their exchanges rhythmically satisfying.

3. Economy of lines

Ephron wastes no words. Every line has a function. It reveals character, advances the conflict, or plants a setup. There are no filler conversations. The discipline is rare and essential. If a line of dialogue does not do at least one of those three things, it should be cut.

4. Verbal conflict disguised as ordinary conversation

Harry and Sally discuss films, restaurants, and mutual friends. But they are never really talking about those things. They are always negotiating the terms of their relationship. This technique—conflict hidden inside the mundane—is Ephron’s signature.

5. A consistent authorial voice

Despite their differences, the characters share a certain quality. All are verbally brilliant, self-aware, and capable of analyzing themselves. It is Ephron’s voice: a universe where characters think and speak with a lucidity the audience finds irresistible.

6. The ping-pong rhythm

Harry and Sally’s dialogue has a precise rhythm: line and counterline without pauses, like a verbal tennis match. Ephron alternates brief lines and rapid, high-energy exchanges with sudden monologues, where vulnerability enters and the register shifts. The contrast between those two rhythms creates the emotional dynamics of the scenes.

How Ephron handles subtext in dialogue

Ephron’s rule makes her characters brilliant at discussing everything except what they truly feel. Harry can analyze other people’s relationships with perfect clarity, but cannot admit that he misses Sally. Sally can articulate exactly what failed with Joe, but cannot admit that she wants Harry.

The gap between intellectual articulation and emotional incapacity is an enormously powerful technique. The characters are perceptive but not wise, eloquent but not honest. The audience sees the contradiction and finds it funny and moving at once.

Dialogue is not conversation. Real conversation is full of hesitations, repetitions, and banalities, while narrative dialogue is compressed conversation in which every line works. A line lives if it reveals something about character, advances the conflict, or could not possibly be spoken by anyone else. If it does none of those things, it is only noise.
