The teaser trailer for Sinister 2 was released only a few days ago, and Blumhouse has now hit us with the first full-length trailer for the horror film. The sequel looks to be building on the mythology first established in the popular 2012 movie. Why does the boogeyman need to take the souls of all these kids? What’s the deal with all the 8mm camera equipment? And what the hell kind of name is Bughuul, anyway? It looks like we’ll get an answer to at least one of these questions when Sinister 2 hits theaters on August 21.
