The challenge

Netflix South Africa needed to cast six couples for The Ultimatum: South Africa Season 1. Previous social campaigns had failed to attract the right personalities, emotional depth and relationship dynamics needed to carry a high tension reality format. The show depends on real conflict, real stakes and real vulnerability. Without the right couples, the season would fall flat. The brief required a complete strategic reset and a casting engine that could reach people who were both willing and suitable to appear on the show.

The strategic insight

People do not sign up for reality shows because of generic calls to action. They sign up when the content feels like it speaks directly to their lives. Relationship based formats thrive when couples see themselves in the invitation. Humour, relatability and honesty break down the social barriers that usually stop people from applying. If the campaign could capture that tone, the right couples would not only notice it, they would act on it.

The idea

We built the casting campaign around a simple guiding thought. Make the audience feel seen. Every piece of content was designed to reflect real relationship habits, tensions and turning points. We used a playful and slightly provocative tone that encouraged couples to ask themselves uncomfortable questions in a light hearted way. The idea positioned the application not as a long shot, but as a natural next step for couples at a crossroad.

The execution

DarkMatter rebuilt the campaign from scratch with a new visual identity, voice and content approach. We produced a full suite of social first assets, including video pieces, short clips and static formats crafted specifically for Instagram, TikTok and Facebook.

The content used humour, self-awareness and culturally relevant language to create familiarity and ease. Captions acted as prompts that mirrored real relationship conversations. Each platform received tailored creative to maximise reach and conversion. The strong performance of the first burst led Netflix to commission four additional waves of content to maintain momentum and deepen the pool of applicants.

The result

The casting campaign exceeded every target set by Netflix.

  • 13.7 million impressions
  • 687,359 engagements
  • 80,023 link clicks
  • 663 completed applications
  • 14 shortlisted couples with strong on screen potential

Netflix received a deep, diverse and emotionally compelling set of couples for final consideration, far surpassing the initial recruitment goals.

Why this matters for your business

This work proves that even the hardest human decisions can be influenced when the message reflects real behaviour and speaks in the audience’s own language. Casting, recruitment and high commitment conversion depend on tone, insight and cultural understanding, not volume alone. If your brand needs to move people from passive interest to active commitment, this approach delivers.
