Film Guides / Genres explained
Horror and thriller
How horror and thrillers create fear and suspense, the main subgenres, the techniques directors use, and landmark films from the silent era to today.
Horror and thriller films both aim to make the audience feel something physical: a racing heart, held breath, the urge to look away. Horror is built around fear of a threat, often something monstrous, unknown or supernatural. Thrillers are built around suspense and danger, usually with a realistic threat and a ticking clock. The two overlap constantly.
How fear and suspense work
Alfred Hitchcock famously explained the difference between surprise and suspense with a bomb under a table. If it explodes without warning, the audience gets a few seconds of surprise. If the audience sees the bomb and the clock while the characters chat on, unaware, the scene generates minutes of suspense. Giving viewers information the characters lack is one of the strongest tools in both genres.
Key techniques
| Technique | What it does |
|---|---|
| Low-key lighting | Deep shadows hide threats and make spaces uneasy; see lighting |
| Sound design and silence | A sudden quiet, a creak or a low drone builds dread; see sound |
| The jump scare | A sudden loud sound and image after a build-up, effective but easy to overuse |
| Restricted point of view | We see only what a character sees, so the edges of the frame feel dangerous |
| The reveal | Delaying a clear look at the threat makes imagination do the work |
| Music cues | Repetitive or dissonant scores signal danger; see film scoring |
Subgenres
Horror:
- Gothic and supernatural: haunted houses, vampires, ghosts. The German silent film Nosferatu (1922) is one of the earliest surviving vampire films.
- Slasher: a masked killer stalking young people, popularized by Halloween (1978) from John Carpenter.
- Creature features: monsters and animals, from 1930s classics to giant sharks.
- Psychological horror: fear drawn from the mind, grief or isolation.
- Folk horror: rural communities, old customs and the unsettling countryside.
- Social horror: fear used to explore real-world issues, as in Jordan Peele's Get Out (2017).
Thriller:
- Psychological thriller: manipulation, unreliable narrators and twists.
- Crime and heist thriller: detectives, investigations and carefully planned robberies.
- Mystery thriller: a puzzle to be solved before time runs out.
- Disaster and survival thriller: people against nature or circumstance.

Why audiences enjoy being scared
Psychologists suggest that horror lets viewers experience fear in a safe setting, with a clear end. The rush of adrenaline, followed by relief, can be enjoyable, especially when shared with a crowd. Watching horror in a full cinema is a distinct experience because laughter and screams are contagious.
Horror films range from mild spooky family stories to intense, graphic films. Check age ratings and content advice before choosing one for a group.
Low budgets, big returns
Horror has a long history of low-budget productions that earn many times their cost, because the genre relies on atmosphere and ideas more than expensive spectacle. That makes it a favorite starting point for new directors. Read how box office works to see why that matters to studios.
