More ‘prankvertising’ at its best – this time to promote the new Carrie film released in October 2013. A New York coffee shop is rigged up with hidden cameras, actors and stunt mechanisms, to give passers by the shock of their lives. Whether staged or not, the reactions look pretty genuine.

The video also takes you behind the scenes on the gag, showing how the coffee shop was set up to make it look like a man is lifted up a wall, chairs and tables are moved across the floor, and books and pictures fly from the shelves.

Reaching 4m views on YouTube within 24 hours of being released, the video has now clocked up a whopping 50m. This is the perfect example of great viral content which appeals specifically to the audience being targeted – those who like to be scared.
