I want the style to be almost like modern film noir, examples of which being the Matrix, as well as Night Crawler, where they both include a lot of chiaroscuro in the way they are lit, and filmed. This should make the mood and atmosphere clear, in that I want it to be dark, sinister and mysterious.
The atmosphere will be made by the setting mostly being at night time, which in the given trailer will contrast lighter scenes to present an element of horror. The atmosphere of night crawler is what I am aiming for, with the serious, almost scary narrative plot, and low key lighting.
The mood will be set in a similar way, as the dark shots, mysterious characters and plot will set it to be sinister and intense. I have been influenced greatly in this by the Matrix, as well as the Dark Knight (mostly the opening to the film).
