Cannes Rewards the Case Study, Not the Campaign

The industry's biggest prize is awarded to a three-minute film about work that a much smaller number of humans actually saw.

A friend called me last Thursday from an edit bay in the Pearl. She was eleven hours into grading a case film, tightening one shot of a phone screen so the engagement number landed on the drum hit. She sounded happy. She sounded wrecked.

The campaign the film is about ran nine days, in one market, on a budget that would not cover a regional furniture chain's spring flight.

The film will be seen by juries in Cannes next week, by every new business prospect that agency talks to this year, and by half the strategists I know, who will watch the winners reel the Monday after and feel briefly bad about their own quarter.

Which is exactly the problem.

Cannes does not judge campaigns. It judges the best three minutes anyone can assemble about a campaign, and assembling those three minutes is a different craft from making the work.

I have watched this from inside agency rooms, where the case film gets planned before the media plan does. That is not a rumor, it is a line item. You decide the story you want to tell a jury, then you build the smallest piece of real world that lets you tell it truthfully. One market. Nine days. A number that is technically accurate and contextually weightless.

Here is the part that gets lost. The case film format rewards three things, and effectiveness is not among them. It rewards a legible problem, a mechanic you can explain in one sentence, and a number that goes up. Work that actually moves a business is usually none of those. It is slow, it is unglamorous, and its results arrive eighteen months later in a spreadsheet with too many confounds to put on a title card.

The brands people cite as proof that advertising works are rarely Grand Prix machines. Patagonia has spent decades being the same company out loud. Duolingo built an audience by posting every single day for years, which does not cut into a hero film. Salt & Straw sells flavor stories out of Portland scoop shops that will never be entered into anything. Their consistency is the strategy, and consistency has no highlight reel.

I am not against the awards. Juries reward ambition, ambition is scarce, and somebody should be protecting it. But we should be honest about which object is being judged, because juniors are watching the reel and learning what the job is.

It rewards a legible problem, a mechanic you can explain in one sentence, and a number that goes up.

My friend sent me the cut at one in the morning. It is genuinely beautiful, and I told her so twice. Barnaby watched about nine seconds of it over my shoulder, concluded the drum hit was not intended for him, and went back to the window.
