The document discusses various elements of mise-en-scène that are commonly used in mystery-thriller films to create suspense and tension. Low key lighting and dark colors are used to hide details and play on fears of the unknown. Props like weapons increase stakes during confrontations. Non-diegetic music and silence are employed to build suspense, while diegetic sounds like footsteps indicate impending scenes. Settings range from urban areas that feel familiar yet dangerous to rural isolation or dystopian futures acting as social commentary. Costumes reflect the time period or indicate a character's morality through bright or dark colors.
