This document discusses the codes and conventions of thriller films. It notes that thrillers typically involve a battle between a protagonist seeking to restore justice and an antagonist seeking to destroy it. Key conventions include crimes or flawed protagonists being exploited by antagonists, narratives with false clues and resolutions building tension, and protagonists often shown in danger. Cinematography aims to reveal clues about antagonists while hiding their identities through shots like silhouettes or from behind. Common thriller themes involve identity, manipulation of perspective, and earlier films' objectification of women.
