The film Saw is a 2004 horror film directed by James Wan. The trailer uses various techniques to establish it as a gory horror film. It features quick cuts and transitions between dark, tense scenes showing victims in peril. Non-diegetic sounds like heartbeats and screams build intensity, while the villain Jigsaw's distorted voice adds mystery. Overlaid text directly tells the audience he is a "madman" and "psychopath" to reinforce the disturbing tone. The trailer effectively uses visuals and audio to draw viewers in and generate fear and suspense around Jigsaw's deadly games.
