The teaser trailer of the film features a scene where two sisters play Bloody Mary in front of a bathroom mirror. To create an unforgettable experience for the movie goers, we encouraged the audience members to play the same game in a public bathroom.

So when they activated the tap for the wash, all the stall doors slams open and all the lights goes off in the bathroom. A LED screen simulates the image of the “entity” on the mirror while the black lights placed in the bathroom displays the hidden promotional message.
