"Halloween" is a short screamer video by YouTuber Matthew Santoro as a little Halloween treat in 2012.
The VideoThe video is shot in the style of silent 1920s films, complete with several jump cuts abundant. A hooded figure walks in the room, getting closer and closer to the camera. As soon as he's close enough (to the point where you think HE'S going to be the screamer), Matthew pops in from the right side with quite a creepy face and lets out a deep bellow. It ends with bloody text reading "Happy Halloween".
NOTE: The following video contains a screamer.
