Nathan Shoop is thirty feet above Sunset Boulevard in a ratty bathrobe, eating cereal in a living room that is three feet deep. Curtains, a lounge chair, a stack of books, a couple of paintings on the wall. Below the window, painted onto the blue shutters, one line of copy: How long can you survive? It is ninety degrees on the street. Shoop has air conditioning and the drivers stuck at the light below him do not. When a reporter stood on the pavement with a whiteboard and asked whether he was bored, Shoop wrote back through the glass: only boring people get bored.

He stayed up there three days to promote The Last House, Louis Leterrier's thriller about a family sealed inside their home with no way out. A drone and a news helicopter circled him. People drove over after being pinged by the Citizen app, which is normally reserved for crime.

Netflix auditioned ten actors and picked Shoop because he was best at seeming like an ordinary man stuck in his house. Four months ago the same company strapped Charlize Theron to a climbing rig and had her scale a rock wall bolted to a billboard in Times Square. That version works and tells you nothing you did not already know, which is that Charlize Theron is a movie star. Shoop is thirty-four, has a producing career, and is not in the film. Casting a man nobody could name was the harder call, because it left the stunt to survive on its idea alone.

Netflix has been buying this stretch of road since 2018, when it offered more than $300 million for Regency Outdoor Advertising and ended up with up to 35 Sunset Strip displays. The site the house sits on is theirs. So the media was free, and what Netflix actually paid for was a set, an air conditioning unit and a man.

On a wall where the options run to LED, projection mapping and a QR code the size of a car, they used a dry-erase marker. Shoop talked to the street through a whiteboard held against the glass, because the character in the film has no phone and so neither did he. A billboard is a one-way object, designed to be looked at by people who have agreed in advance not to look at it. This one looked back, and waved, and answered when you wrote to it. That is why the news crews covered it as an event rather than a campaign.

The Last House started streaming the following morning. There was no ticket to sell and no opening weekend to protect. Everyone who drove past the sign already owned the film, four taps away inside a subscription they were paying for that month regardless.

So the job was not getting the product to the customer. The product was in the house. The job was making anyone care it was there, which is the problem Netflix has had all year: Kevin Hart's Me Time opened in 2022 to 59.23 million views in three days, and his new one, 72 Hours, did less than half that. The New York Times called the billboard a rare play from a company that usually lets the algorithm do the heavy lifting. You only build a house on Sunset when the row of thumbnails has stopped doing the job on its own.

Shoop had no Wi-Fi up there and no phone, so for three days the one man in Los Angeles paid to sell Netflix was the only one who could not watch it. A reporter asked him by whiteboard what he would put on if he could.

He wrote back: 72 Hours.

Nobody showed him a thumbnail. He was sealed in a box above the traffic with a bathrobe and a stack of books, and he still reached for the biggest thing on the service. That reflex is the entire business, and Netflix spent this summer failing to trigger it.
