Missing People's 'Based on a True Story' turns true-crime tropes back on the viewer
A film that looks like a true-crime pitch meeting — until the punchline lands: every 'case' the producers mock is a real missing person.
Missing People
What it had to solve
True crime is one of the UK's most popular entertainments — Missing People cites 49% of the population watching daily — while someone is reported missing every 90 seconds. The charity saw real families' stories being reshaped for clicks and ratings, so it joined BBH London and Sharon Horgan's Merman to hold a mirror up to the genre.
How it works
True crime has become mainstream entertainment: Missing People's campaign cites 49% of the UK population watching it daily, while someone in the country is reported missing every 90 seconds — nearly 160,000 families a year living the reality behind the genre. The charity's observation was uncomfortable: cases get attention when they are packaged as compelling content, not because every missing person deserves it.
The campaign's centrepiece film borrows the genre's own vocabulary. In a writers' room, producers dissect potential cases with clinical detachment, debating which stories have the right arcs, pacing and marketability for the next hit series. The tension plays as dark comedy until the reveal: every case they have been mocking up is real. The discomfort lands precisely because viewers recognised their own consumption habits in the room.
Around the film, the campaign extended the idea into the media ecosystem that feeds true crime: an empty boxset titled 'Top Five Cases You Won't See On TV' sent to true-crime influencers and outlets, out-of-home executions showing real case files covered in flippant producer notes, and a Responsible Narratives Charter inviting creators to commit to ethical storytelling. Families with lived experience co-created the work, grounding the satire in authenticity.
Why it lands
- Satire disarms defensiveness: fans of the genre can laugh at the pitch room before the reveal makes them squirm.
- The reveal — every case is real — moves the discomfort from the screen into the room where the genre is consumed.
- The Charter turns the critique into an actionable commitment instead of a rant, so the campaign changes how stories get told.
- Building the film with the families involved keeps the satire aimed at the system, never at the people at its centre.
What it did
The film won a Cannes Lions 2026 Gold in Film (Use of Humour). The Charter gives creators a concrete commitment — tell true stories ethically, respect families, avoid harmful speculation — while the charity's message reframes the genre's responsibility: these are not plotlines but real lives, and they are never entertainment.
What you can take
To criticise a genre people love, borrow its grammar: satire that looks exactly like the thing it condemns lets the audience feel the discomfort themselves instead of being lectured.
Since then
The campaign won a Cannes Lions 2026 Gold Lion in Film for Use of Humour, and Missing People's own page for the work opens with a warning that the film may be upsetting. The charity frames the aim as changing the attention economy around disappearances: every missing person deserves the right kind of attention, and harmful speculation adds pressure to families at their hardest moment. Family members who lived through high-profile cases publicly endorsed the campaign, saying it showed what their lives have been like under public scrutiny.
