Following scene:

We filmed me walking up some stairs so it shows how obsessive the stalker is: he follows me everywhere. This is a medium shot. as i start going up the stairs, I stop and turn round to face the camera because i suspect something. This creates suspense and as it is coming towards the end of the trailer it makes it seem as though everything will be resolved. As soon as i turn round, the camera turns off and the screen goes completely black which leaves a cliff hanger.
