A casting brief should remove uncertainty
The best casting brief is not the longest one. It is the brief that lets a model, agent or producer understand the job without guessing. State the brand, production date, city, expected hours, creative category, wardrobe needs, media deliverables and the broad audience the campaign is trying to reach.
If a campaign includes stills and video, say so before casting. Product handling, direct-to-camera delivery, walking, dance or repeatable ecommerce posing are performance requirements that shape who is genuinely suitable.
Usage belongs in the brief
A model fee cannot be scoped responsibly without understanding where the work will appear. Note whether assets are intended for organic social, paid media, ecommerce, retail displays, outdoor, print or broadcast, with expected territory and duration.
South African brands get better shortlists when the brief explains the problem the model needs to solve. Specificity attracts relevant talent without forcing the creative into one narrow look.
