Who writes the script?
Short Answer:
The script can come from you, your agency, or the production company — or a mix of all three. Many businesses provide the key messages and let the production team shape them into a shootable script, interview questions, or voiceover. What matters is that whoever writes it understands both your goal and what will actually work on camera.
Overview
Scripting is usually a collaboration. A brief or rough draft from the client is turned into a production-ready document — one that accounts for pacing, visuals, and how the words will sound spoken aloud, not just read on a page.
Detailed Explanation
Who typically contributes
You or your team: the core messages, facts, and tone of voice.
An agency (if involved): the creative concept and campaign messaging.
The production company: turning that into a shootable script, interview questions, or voiceover — and flagging what will not work on camera.
For interview-led films there may be no formal script at all. Instead, a set of carefully written questions guides the conversation, and the story is shaped in the edit.
Example
For a corporate explainer, a client might supply bullet-point messages; the production company then drafts a tight voiceover script and on-screen text, and refines it with the client before filming.
