Ok - I'm pretty sure that I just saw this trailer on the DVD for
Doghouse, so it's possible that it's from the UK (I can't believe I didn't write the title down :mad:) - So that means that it's either released in the UK or about to be released in the UK. Either that or that just means that it's an indie horror flick (really helpful, I know) and is new (so released sometime 2008 - present).
Anyway - It has a low-budget style, kinda like
Paranormal Activity, but the hand held camera is held by the director and not one of our characters (if you know what I mean)...
There are three characters, a girl, her boyfriend/fiance/husband and his friend. The friend is staying at the couple's house and is clearly possessed - He sees demons or ghosts when the lights are off. Of course, the girl just wants to throw him out, but the friend won't do it.
It's call something to the effect of...
The Haunting of [a guy's name]
The Possession of [a guy's name]
The Exorcism of [a guy's name]
Thanks so much for your help!
