Thrillers use certain conventions to build tension and suspense. Editing techniques and low key lighting create an uneasy atmosphere. The antagonist has a criminal or psychological motive that drives them into conflict with the protagonist. Examples from films like Panic Room, Fatal Attraction, and The Shining demonstrate how close ups, music, and isolated settings are used to focus on characters' emotions and highlight danger and uncertainty in the story. Static shots, unexpected dialogue, and rapid scene changes also build tension between protagonists and antagonists.
