Whether you’re plotting a dystopian thriller or a heartfelt coming-of-age drama, one of the first (and most important!) decisions you’ll make as a screenwriter is this: What genre am I writing in?

Genre isn’t just a label slapped on your script to help it find a home on a streaming platform. It’s more than that! It’s the heart of your story’s identity. 

Genre shapes your characters, your tone, your structure, and even your audience’s expectations. And if you’re serious about screenwriting, understanding genre is essential. 

In today’s blog we’re talking about, you guessed it, genre! Get ready for your definitive guide to genre in screenwriting. We’ll explore what it is, why it matters, how to use it, and how to bend it to your will.

Let’s get started…

What is Genre, and Why Does it Matter?

Genre is a storytelling framework. It’s a set of conventions including tropes, themes, tones, and structures that help audiences know what kind of emotional journey they’re signing up for. 

Think of genre as a kind of shorthand. When someone hears ‘romantic comedy’, they expect witty banter, awkward meet-cutes, and a satisfying kiss in the third act. When they hear ‘horror’, they brace for tension, dread, maybe topping it off with a few sleepless nights.

For screenwriters, genre is both a creative compass and a marketing tool. It helps us:

  • Focus on our storytelling choices (What kind of conflict? What kind of resolution?)
  • Communicate with collaborators (directors, producers, actors)
  • Position our scripts in the industry (pitching, festivals, competitions)

In short: genre gives our stories a home and helps it find its people.

The Function of Genre: A Contract Between Writer and Audience

Here’s the thing about genre that often gets overlooked: it’s a promise.

When you write in a particular genre, you’re entering into a contract with your audience. You’re saying, “Here’s the kind of experience you’re going to have.” And if you break that promise without purpose or payoff you risk losing their trust.

Don’t get me wrong, that doesn’t mean you have the follow every rule to the letter. But it does mean you need to understand the rules before you break them. Audiences are savvy; they know when something feels ‘off’, even if they can’t articulate why.

So, whether you’re writing a gritty crime drama or a whimsical fantasy, ask yourself this: what am I promising my audience? And am I delivering on that promise?

Common Film Genres and Their Conventions

Let’s break down some of the most popular film genres and what makes them tick. We’re even throwing in some standout examples of each!

Action

Core Conventions

High stakes, physical conflict, fast pacing, clear heroes and villains.

Audience Promise

Adrenaline, spectacle, and a satisfying showdown.

Examples

Film: The Raid, Skyfall, Atomic Blonde, The Equalizer

TV Shows: Strike Back, Banshee, Warrior, Bodyguard

These stories are all driven by physical intensity, often featuring lone heroes, tactical showdowns, and relentless pacing.

Comedy

Core Conventions

Exaggeration, misunderstandings, irony, and timing.

Audience Promise

Laughter, levity, and often a deeper truth beneath the jokes.

Examples

Film: Palm Springs, The Nice Guys, Death at a Funeral, In the Loop

TV Shows: Derry Girls, What We Do in the Shadows, The Good Place

All these comedies range from absurdist to satirical, but all use humor to explore human behavior and social norms.

Drama

Emotional depth, character-driven conflict, moral dilemmas.

Audience Promise

Catharsis, connection, and a mirror to real life.

Examples

Film: The Lost Daughter, Aftersun, A Separation, The Wrestler

TV Shows: Rectify, The Leftovers, Unorthodox, Somebody Somewhere

Dramas tend to be emotionally rich, often slow burning, and deeply character-focused, exploring grief, identity, and transformation.

Science Fiction

Futuristic tech, speculative worlds, philosophical questions.

Audience Promise

Wonder, imagination, and a lens on humanity.

Examples

Film: Coherence, Aniara, Prospect, I am Mother

TV Shows: Counterpart, Dark, Foundation, Tales from the Loop

Sci-fi stories lean into speculative ideas, alternate realities, and philosophical dilemmas, often with a grounded or cerebral tone.

Horrors span psychological, supernatural, and body horror, often using atmosphere and ambiguity to unsettle its audience.

The Power of the Mashup

Now here’s where things get really fun!

Some of the most memorable films in recent years have come from genre mashups; stories that blend two or more genres to create something fresh, surprising, and emotionally layered.

Think about it:

⚫️ Sci-Fi Western: Westworld, The Mandalorian

⚫️ Horror-Comedy: Shaun of the Dead, Get Out

⚫️ Fantasy Drama: Pan’s Labyrinth, The Shape of Water

Genre-blending allows you to subvert expectations while still delivering on the core emotional beats your audience craves. It’s also a great way to stand out in a crowded market.

Just remember even in a mashup, one genre usually takes the lead. Know which one is your story’s spine and let the others support it.

Genre and Screenwriting

Okay, all this stuff is great and everything, but how do you actually use genre when writing your screenplay? This is why we’re all here, right?

Here is our five-step approach to using genre the right way:

1. Choose Your Primary Genre

Start by identifying the emotional experience you want to create. Is it fear? Laughter? Awe? That’s your genre foundation.

2. Study the Conventions

Watch films in your chosen genre. Read scripts. Notice the patterns in story structure, character types, visual motifs and dialogue rhythms.

3. Use Conventions as Tools, Not Crutches

Genre conventions are there to guide, not limit. Use them to shape your story, but don’t be afraid to twist them in unexpected ways.

4. Signal Your Genre Early

Your opening pages should clearly establish the genre. This helps readers, producers, and audiences know what kind of story they’re stepping into.

5. Deliver the Emotional Payoff

Whatever your genre, make sure you’re delivering the emotional experience it promises. That’s what keeps audiences coming back.

FAQs

What are the 5 main film genres?

While there’s some debate, the five most commonly cited are:
– Action
– Comedy
– Drama
– Horror
– Science Fiction

These serve as umbrella categories for countless subgenres and hybrids.

What is a genre mashup?

A genre mashup is a story that blends two or more genres, like a romantic comedy or a sci-fi thriller. It allows writers to explore fresh territory while still grounding the story in familiar emotional beats.

Is it okay to write a screenplay that doesn’t fit into a specific genre?

Absolutely, but be strategic. If your story defies genre, make sure it still delivers a clear emotional arc. And be prepared to explain its tone and audience in your pitch.

What is the difference between a genre and a subgenre?

A genre is a broad category (e.g., horror), while a subgenre is a more specific flavor within that category (e.g., psychological horror, slasher, supernatural horror). Subgenres help you fine-tune your story’s tone and audience.

Conclusion

Genre is more than a label; it’s a creative playground. It gives you a framework to build within, but it doesn’t have to be a cage. In fact, the most compelling stories often come from writers who understand genre deeply and then push its boundaries with intention and flair.

Whether you’re writing a tight psychological thriller or a sprawling sci-fi romance, genre helps you shape your story’s tone, structure, and emotional core. It’s how you communicate with your audience before they’ve even read a word of your script. It’s how you signal what kind of journey they’re about to take.

But here’s the secret: genre is just the beginning. Once you’ve mastered the conventions, you can start to play. You can twist expectations, blend styles, and create something that feels fresh and personal. You can write a horror film that makes people cry, or a comedy that makes them think. You can take familiar ingredients and cook up something entirely new.

So don’t be afraid to experiment. Watch widely. Read scripts across genres. Ask yourself what kind of emotional experience you want to create and then use genre as your toolkit to build it.

And remember: every genre has room for your voice. Whether you’re drawn to gritty realism, magical worlds, or sharp satire, there’s a place for your story. The key is to be intentional. Know what you’re promising your audience, and deliver it with heart, clarity, and craft.
