The teaser trailer for Fatal Attraction uses various cinematic techniques to build tension and unease. Low camera angles are used to make the audience feel vulnerable during violent scenes and when Alex is behaving unpredictably. Close-ups and shot-reverse-shot create intimacy during early scenes between Alex and Dan but also show Beth's tense body language when confronting Alex. Dark lighting and ominous music portray Alex as increasingly unhinged as she disrupts the family through obsessive phone calls and kidnapping Dan's daughter. The teaser cuts between scenes of the family's initial happiness and the growing chaos caused by Alex's unstable behavior, teasing the film's transformation from romance to psychological thriller.
