The document discusses techniques used in filmmaking, including camerawork, editing, lighting, sound, and costume design. It analyzes how these techniques are used in the films The Bourne Legacy, The Apparition, and Silent Hill 2 to create atmosphere, develop characters, and elicit emotions from audiences. Specifically, it notes how The Apparition uses low-key lighting to create a dark and uncertain atmosphere, and how Silent Hill 2 uses simple costumes in dull colors to convey a dirty, decaying effect. The document concludes that these psychological thriller techniques will be useful for creating an unsettling teaser trailer that teases audiences without making every scene predictable.
