Ad's Campagin
The ad begins with the peacefully showing footage of evening skies as a quiet piano piece plays. Eventually, the ad moves on to a footage of babies giggling and playing with each other. however, after about 26 seconds, a picture of Regan MacNeil from The Exorcist appears and zooms normally though with the same scream from The Maze and other screams are mixed. The ad also ends with a message telling the viewer to have a happy Halloween. It was part of the #NotSoSweet campaign.
