Codes and Conventions of the Thriller Genre

1. Narrative Structure

Thrillers usually follow a structure that builds suspense and tension. There is often a mystery, crime, or secret at the core, with rising action leading to a dramatic climax. The story keeps the audience guessing with twists, turns, and unexpected developments.

2. Characters

Protagonist/Hero: Often intelligent or resourceful, trying to solve a problem or survive danger.

Antagonist/Villain: Can be a criminal, psycho, or conspirator; often mysterious or threatening. Often a group of villains as well.

Supporting Characters: Sometimes allies, sometimes red herrings to mislead the audience.

Victim / Target: Someone in danger or at risk, whose situation drives the tension. Their vulnerability increases suspense.

Detective / Investigator: A character seeking to solve a crime or uncover secrets. Can be professional (police, spy) or amateur (journalist, friend).

Anti-Hero: A flawed main character who may break rules or act unethically but still engages the audience.

Corrupt Authority Figure: Someone in power who hinders the protagonist, hides secrets, or is involved in the crime.

3. Themes

Common themes include crime, revenge, espionage, murders, psychological tension, justice, and moral ambiguity. Psychological thrillers focus on mind games and mental states, while action thrillers focus on danger and physical conflict. Horror thrillers focus on the danger from the supernatural entity or killer, while also creating anticipation for its next appearance and the way to come around.

4. Settings

Settings often create unease or danger, isolated houses, dark alleys, abandoned buildings, or high-stakes locations. Everyday locations can also be used to create tension through subtle threats.

5. Cinematography & Visual Codes

Lighting: Low-key, dim, or shadowy lighting to create suspense.

Camera Angles: Low and high angles to show power or vulnerability; close-ups to emphasize fear or emotion.

Framing & Movement: Tight frames, tracking shots, or handheld cameras to create tension and immersion.

6. Sound & Music

Music and sound effects are used to build suspense, signal danger, or manipulate audience emotions. Silence can also be a powerful tool to increase unease.

7. Editing & Pacing

Fast cuts in action sequences increase tension, while slower pacing in suspenseful scenes builds anticipation. Cross-cutting between events can heighten anxiety and keep viewers engaged.
