What lies beneath - techniques

The most notable difference in the movie was the silence. I'd guess that about 50% of the movie was completely silent except for breathing, footsteps, creaking doors... wonderful. Seems that lately the powers-that-be just have to fit every second of the soundtrack into the movie (seems they should since now-a-days there's commercials for the soundtrack separate from the movie in many cases) in order to boost the spooky level... it rarely works. The silence in the movie just added to that tension in your shoulders and made you slowly edge up on your seat.
