This document discusses conventions of thriller films. It provides examples from American Psycho, Se7en, and The Ring to illustrate common thriller elements. These include opening title sequences over images or plain backgrounds, films being distributed by major studios, settings in cities and houses in America, use of mise-en-scene like costumes and props/colors to characterize villains and set dark, scary atmospheres, and inclusion of sinister non-diegetic music to build tension from the beginning.
