Getting a Performance from a Child

Once you've set up the right conditions — a trusting, playful, low-pressure space — you need practical techniques to actually get the moment on camera, because a child often can't reproduce a scripted performance the way an adult can. Great directors of children have a bag of tricks for this, and none of them involve giving the kid more acting notes. Instead, they engineer the situation so the truthful reaction happens for real in front of the lens. The common thread is that you take the burden of "acting" off the child and put it onto the setup: rather than asking the kid to pretend to be surprised, you actually surprise them; rather than asking them to remember a line, you feed it to them a beat before. You do the technical work so the child only has to react honestly. That's the whole secret of the toolbox.

The on-set toolbox

Practical techniques that work with children:

• Feed lines live. Instead of making a young child memorize and perform dialogue (which often goes stiff), say the line to them a beat before and have them repeat it naturally, or have an off-camera actor cue them. You cut around it. This keeps them present instead of reciting.
• Engineer real reactions. If you need genuine surprise, delight, or a laugh, actually create it on set — a real surprise, a funny off-camera moment, a game — and let the camera catch the authentic reaction rather than a performed one.
• Direct off-camera and in the moment. Talk to the child during the take, quietly guiding them in real time ("now look at the door... now you hear the sound..."), which many kids respond to far better than pre-take notes. You remove your voice in post.
• Control the eyeline and give them something real to look at. Kids struggle to imagine a sightline. Put a real object, a real person, or something interesting exactly where they need to look, so their gaze and reaction are genuine.
• Use the reactions of others. A child mirrors the energy around them. An off-camera actor or crew member genuinely engaging with them can pull a real emotional response the child gives back to camera.
• Shoot their coverage generously. Get plenty of the child reacting, listening, and being — these truthful in-between moments are often more valuable than the scripted lines, and give your editor gold to build the performance from.

Build the performance in the edit

Here's the professional secret that ties the whole approach together and takes the pressure off both you and the child: a child's screen performance is very often built in the edit, out of many real moments, rather than delivered whole in a single take. Adult performances can be captured largely intact — the actor plays the scene, you get it. With children, you're usually gathering: a true reaction here, a natural line reading there, a perfect look in an unguarded moment, a spontaneous bit of business you didn't plan — and your editor assembles those genuine fragments into a seamless, believable character. This changes how you shoot. You stop trying to force one flawless take out of the kid and start hunting for real moments to collect. You keep the camera rolling between "action" and "cut" to catch the unguarded stuff. You shoot lots of coverage and reaction, knowing the gold is often in the edges. You engineer real reactions and grab them however they come, in whatever order. And you protect the child from the pressure of "nailing it," because they don't have to — you and the editor will find the performance across everything you captured. This is also why the earlier chapters matter so much: a trusting, unpressured, rested child (Chapters 6 and 8) gives you far more usable real moments than an anxious, over-directed, exhausted one, and the limited hours (Chapter 4) push you to gather efficiently while the kid is fresh. Directors who understand this work with children joyfully rather than anxiously, because they've reframed the job: not "get the child to deliver the scene" but "create the conditions for real moments and capture as many as you can, then build the performance." Take the acting off the child, engineer the truth, roll generously, and assemble the magic in post. Do that, and even a first-time kid with no technique can end up giving one of the most memorable performances in your film. In the next chapter we tackle the hardest and most sensitive version of all this: emotional and difficult scenes.
