Extremely Convincing Horror Movies People Thought Were Real

This weekend, Blair Witch — a sequel to the ‘90s found-footage classic The Blair Witch Project — opened in theaters. The horror story picks up with the brother of missing student filmmaker Heather Donahue searching for his sister in the dark Maryland woods.

The original film used what is considered a prototype of viral marketing. Directors Daniel Myrick and Eduardo Sánchez created a website with fake police reports and newsreels to spread word about the film, which they also promoted as based on real events during in-person appearances. The realistic marketing tactics had audiences convinced, and they entered the theater believing the terrifying events they were watching on the big screen really happened.

The 1999 movie isn’t alone, however. Several other horror films had audiences believing they were watching something brutally real. Here are just a few extremely convincing horror movies that fooled people.
