How to show a phone screen in a film

A phone in the shot looks simple until you have to shoot it. The text has to arrive on the beat, the screen has to read clearly on camera, and it has to look identical on take seven as it did on take one. There are three common ways to get a phone screen into a scene. Each trades control, cost and time in a different place.

Method 1 — Replace the screen in post

The phone is shot with a blank or marked screen, and the message graphics are tracked and composited in post-production. You get complete control over the final look and can change the text late. The cost is time and VFX work, and the actor has no live screen to react to — you'll need to direct their eyeline and timing without it.

Method 2 — Looped or pre-made playback

A video of the screen plays on the prop phone, often on a loop, and the actor performs around it. It's quick and needs no post work, but timing is fixed: the screen does what the video does, so the performance has to hit the video's beats — and a take that runs long can break the illusion.

Method 3 — A cue-controlled prop-phone app

A prop-phone app draws fictional screens on the actor's phone and lets someone off-camera cue each event — the typing indicator, the message, the incoming call — at the right moment. Because the screen responds on cue rather than playing a fixed clip, the performance sets the timing. The discipline you take on is keeping the phone's starting state identical between takes. CuePhone is the app we're building for exactly this: prepare the scene, cue it with GO, and reset to the same starting screen for each take. Weighing the options?

Continuity: what must not drift

Whatever the method, decide the details that stay fixed and treat them like any other continuity item:

• The clock, battery and signal — they appear in frame and between cuts.
• The conversation shown — which messages are already on screen at the start of each take.
• Brightness and orientation — so the screen reads the same from setup to setup.
• The starting state — every take begins from the same screen.

Camera: test before the shoot day

Phone screens refresh at their own rate, which can interact with the camera's frame rate and shutter and show up as flicker or banding. How much depends on the phone and the camera, so test the exact combination in advance rather than assuming. Shutter angle is the first thing to adjust — our free shutter angle calculator converts angle and frame rate to shutter speed. No app can promise a screen is free of this on every camera, so a quick test on your own setup is the only reliable answer.

Legal: real brands and logos

Showing a recognisable messaging service, bank or social app can raise clearance questions. Many productions use generic look-alike screens or clear the real thing. Ask your production's legal or clearance team before you commit. CuePhone ships generic look-alike screen styles with no real logos or brand names for exactly this reason.
