Milind Rau, the director of Aval, Gruham, The House Next Door talks about the craft involved in directing a horror film. How he alternated between letting the various departments do their own thing and micro-managing it all. He explains what he did in the areas of colour, sound design, background score, cinematography and editing -- and how these (and other departments) came together in the pre-interval exorcism sequence. (He talks about this scene in detail.) He tells how he tried to second-guess the viewer in terms of the scares. And about the classic horror films (The Exorcist, The Omen, Ringu) he used as a reference point, and also paid homage to.
