The production brief is the document that tells a production company what the project is, what it needs to achieve, and what constraints it operates within. A good brief makes the production company\'s job possible. A bad brief makes it difficult in ways that compound through every subsequent phase.
Most briefs fail not because the writer is inexperienced but because the writer is too close to the project. What is obvious to someone who has been living with the brand strategy for six months is not obvious to a director reading the brief for the first time. The brief must close that gap.
What a brief must include
Project overview: what is the commercial for, what is it selling, and what is the campaign context? Target audience: who is the viewer and what do we know about them? Single message: if the viewer remembers one thing from the film, what should it be? Mandatories: what must appear (product shots, logo, legal disclaimers) and what is prohibited? Deliverables: what formats and durations are required? Timeline: when does the film need to be delivered? Budget: what is the production budget?
Every one of these sections represents a decision that has downstream consequences. Missing any of them forces the production company to make assumptions — assumptions that will be wrong in ways that only become visible later.
Why "make it go viral" is not a brief
"We want it to go viral." "We need something emotional." "Make it premium but accessible." These are outcomes or tonal directions, not briefs. A brief tells the production team what they are working with. Aspirational statements about what the finished film will achieve tell them nothing about what the brief actually requires.
The test of a brief: can a director read it and know what film they are being asked to make? If the answer is no, the brief is not finished yet.
The five mistakes agencies make most often
First: writing the brief after the creative concept is already fixed. The brief should inform the concept, not justify it retrospectively. Second: burying the single message inside three paragraphs of brand strategy. Third: leaving budget out entirely, treating it as something to be "discussed." Fourth: omitting the timeline or listing aspirational rather than realistic dates. Fifth: not specifying the deliverables — different platforms require different aspect ratios and durations, and a brief that does not address this creates work later.
How to test a brief before sending it
Give the brief to someone who knows nothing about the project and ask them to describe the film they would make from it. The gap between their answer and your expectation is the gap the brief has not yet closed. Close that gap before the brief leaves the building.
