Halloween Horror Nights Singapore 2015

An ad for Universal Studio's Halloween Horror Nights in Singapore was aired in 2015, and became well known for its effective jump scare.

The Ad
This ad, for obvious reasons, contains a viewer discretion notice at the first few seconds. After it disappears, we're treated to the moon going through an eclipse-like effect called "Blood Moon". This summons a number of dark figures who wreck havoc. Eventually, the ad displays a graphic shot of a body being dragged off, followed by the attraction advertisement. Just as the ad seems to stop, we are assaulted by a bloodied face roaring into the camera before abruptly cutting off.
