I feel like I'm going crazy, I've been looking for the horror movie NIJ and HJW are watching during episode 4 at the 30:20 mark (approximately) and I CAN'T FIND IT! At first I thought it was like Return of the Living Dead, but it looks like an exorcism kind of horror movie and not a zombie one. So I thought it might be Evil Dead or an older rendition of Amityville because of the attic scene. However nothing came of my frantic looking at stills from those movies. I also looked at stills from The Exorcist to see if it could be a rip-off, but I don't think it is... 

Anyway, I hope I'll find horror movie lovers or sleuths to help me find it before I become crazy.

I love horror movies and I also wanted to see if the director/author added subtext with the movie they decided to play. I feel like it should  have some meaning...
