Research & Planning: Sinister

Over the weekend I went to see the new horror / thriller "Sinister".  I found it a useful resource for my trailer as its combination of graphic content and stalker induced tension created a good atmosphere that was similar to the one I wanted to create in our trailer.
     However, I wouldn't contain as much blood and gore in my work as I want to stick to the psychological side of thrillers.  I would, however, include the technique in which the camera filmed whilst a torch was shone allowing the audience to see a circle on screen that is surrounded by darkness, allowing us to easily build up tension.
