What Is a Reaction Shot?
A reaction shot is a shot of a person's response to what is happening, their face as they hear a line, watch an event, or absorb bad news, cut in to show the audience how to feel about the moment. Someone delivers a gut-punch line; you cut to the listener's face. That listener's reaction often carries more weight than the line itself, because the audience watches a human process the moment alongside them.
It is a specific kind of cutaway, the something else you cut to is a person reacting, and it is one of the most quietly powerful tools in editing.
Why the reaction often beats the action
Here is a thing that surprises new editors: the most emotional shot in a scene is frequently not the event, it is the face watching the event. We are wired to read faces. A close-up of someone's eyes welling up tells us more about what just happened than the thing that happened.
MasterClass traces this back to the basic discovery that editing, not just performance, creates meaning. A reaction shot lets the editor decide the emotional reading of a moment after the fact, just by choosing whose face to cut to and when.
The Kuleshov effect: where reaction shots get their power
In the 1910s and 20s, Soviet filmmaker Lev Kuleshov ran an experiment that still underwrites every reaction shot ever cut. He took a single, neutral close-up of an actor's expressionless face and intercut it with three different shots: a bowl of soup, a girl in a coffin, a woman on a couch.
Audiences swore the actor was brilliant. They saw hunger when his face preceded the soup, grief when it preceded the coffin, desire when it preceded the woman. But it was the same shot of the same blank face every time. As Wikipedia describes the Kuleshov effect, viewers derive more meaning from the interaction of two sequential shots than from either shot alone.
For an editor, the lesson is enormous. The meaning of a reaction shot is set by what it is cut against. The same face reads as fear, love, or suspicion depending entirely on what you show before or after it. You are not just showing a reaction. You are authoring it.
The Spielberg face and the modern reaction shot
The technique never went away, it got refined. StudioBinder points to what some call the 'Spielberg face,' the slow push-in on a character's awestruck or terrified expression as they look at something off screen, in films like Close Encounters of the Third Kind. We feel the wonder before we ever see what they are seeing, because the reaction primes us.
The reveal-then-reaction, or reaction-then-reveal, is a fundamental rhythm of cinema. Withhold what they are looking at, hold on the face, let the audience's imagination run, then show, or never show at all, and let the reaction be the whole scene.
When to use a reaction shot
- To tell the audience how to feel. Cut to the right reaction and you set the emotional reading of the moment.
- To make a line land. A great line is often better witnessed than delivered, the listener's face sells it.
- To build a scene's pulse. Cutting between speaker and listener is the basic rhythm of dialogue, and reaction shots are half of it.
- To create tension or comedy. A held reaction, a stunned silence, a slow burn, can be funnier or scarier than any action.
- To cover an edit. Like any cutaway, a reaction shot is a clean place to hide a join in the main audio.
Common mistakes
The most common error is cutting away to a reaction at the wrong moment, leaving the speaker's best line too early to catch a nod. Time the reaction to the beat, you usually want to hear the line, then see it land, or see the face brace just before it. Cutting to the reaction a beat too soon or too late kills the moment.
Another is the dead reaction, cutting to a listener who is not actually reacting. If the face is blank and the context does not supply the meaning, the cut feels pointless. The Kuleshov effect helps, but it is not magic; the cut around it has to do its job.
And do not overcut. If you bounce to a reaction on every single line, the scene gets seasick. Reactions are punctuation, not the whole sentence. Use them on the lines that matter.
A worked example
You are cutting a two-person interview, a daughter and her father, talking about a hard year. The father says, quietly, 'I did not think I would make it.' You have the daughter on a second camera, listening.
Stay on the father and it is a sad line. But you cut, on the word 'make it,' to the daughter's face, and you see her eyes fill, her jaw tighten, the effort not to cry. Suddenly the line is not just sad, it is shared. The audience feels the weight through her. You did not change a word he said. You chose whose face carried it, and that choice is the edit. That is a reaction shot, and the Kuleshov effect, working in your favor.
Finding and timing reactions in the pre-edit
Reaction shots demand two things from an editor: the right reaction must exist in your footage, and it must be timed to the exact beat. The first is a coverage and logging question, the second is a precision question.
This is where reading your footage as text pays off. When you work through an interview transcript and mark the lines that hit hardest, you know exactly where you will want a reaction, the gut-punch lines are right there. And with word-level timecodes, the moment of the line is linked to the precise frame, so timing the cut to land on the word is straightforward. With ScriptCut you read the conversation as a transcript, mark the lines that carry the emotion, and play any moment to feel the beat, then arrange the story and export a ready-to-cut timeline to DaVinci Resolve, Premiere, or Final Cut, where you place the reaction shots and trim them to the frame. The decisions, which lines need a reaction and where, get made in the pre-edit; the frame-precise cut happens in the NLE. See how to cut a documentary interview and how to edit multicam interviews.
Walter Murch, the editor of Apocalypse Now, ranked emotion as the single most important thing a cut can preserve, above story, rhythm, and continuity, in his book In the Blink of an Eye. A reaction shot is one of the purest ways to put that principle to work. Cut to the right face at the right moment, and you do not just show the audience what happened, you tell them how to feel about it.

Frequently asked questions
What is a reaction shot?
A reaction shot is a shot of a person responding to an event or a line, their face as they hear news, watch something happen, or absorb a moment. It is a type of cutaway that shows the audience how to feel about what just occurred.
What is the Kuleshov effect?
The Kuleshov effect is the discovery that viewers derive meaning from the interaction of two shots, not from one alone. Lev Kuleshov intercut the same neutral face with a soup, a coffin, and a woman, and audiences read hunger, grief, and desire into the identical expression.
Why is a reaction shot often more powerful than the action?
Humans are wired to read faces, so a close-up of someone watching an event often carries more emotion than the event itself. The reaction lets the audience process the moment through a human, and lets the editor set the emotional reading of the scene.
What is a common mistake when cutting reaction shots?
Timing them wrong, cutting to the reaction a beat too early or too late, so the line and the response do not connect. Other mistakes include cutting to a blank, non-reacting face, and overcutting so the scene bounces between faces on every line.
