No Metro is a ghost train that you can hear, but you cannot see.

There are loudspeakers and hidden cameras located in the busiest metro station in the city.

Passengers are waiting for their train.

We set off our progressive sound programme that accurately reproduces the sound of the metro: the train approaching, the brakes, the doors opening, the doors closing, the train leaving the station.

Just like a ghost! Passengers could hear it but they couldn’t see it.

And at the peak moment of surprise and expectation, the legendary Ghostbusters sound track begins to play while the display panels in the station announce the remake of the film.

The video was shared across social networks, announcing the existence of paranormal phenomena in Madrid’s Metro.

Ghostbusters was back on our cinema screens after 20 years, and we had to devise a special action to promote the release. The challenge? To create and develop a campaign that could communicate the release of the new film and at the same time attract the attention of both the fans of the first sagas, as well as a new generation.
