This trailer has given us the idea of the use of smoke and monster noises. the smoke will prove very beneficial for our opening sequence were we are now allowed to have a larger number of zombies who wont need make up or contact lenses considering there faces will be hidden by the smoke, yet the zombie like position will clearly show that they are zombies. The idea of monster noises enhances the tension and horror of the zombies, allow us to create a more realistic and terrifying opening sequence.
