If a writer of prose knows enough about what he is writing about, he may omit things that he knows and the reader, if the writer is writing truly enough, will have a feeling of those things as strongly as though the writer had stated them. The dignity of movement of an iceberg is due to only one-eighth of it being above water.
~ Ernest Hemingway, Death in the Afternoon
As screenwriters, we’re often told to “show, don’t tell.” But what if showing isn’t just about what’s on the page, but also about what’s implied? This is where Ernest Hemingway’s powerful Iceberg Theory (also known as the “theory of omission”) comes into play, a concept every screenwriter should master.
Hemingway famously said, “If a writer of prose knows enough about what he is writing about, he may omit things that he knows and the reader, if the writer is writing truly enough, will have a feeling of those things as strongly as though the writer had stated them. The dignity of movement of an iceberg is due to only one-eighth of it being above water.”
This isn’t just a poetic turn of phrase; it’s a profound insight into human psychology and storytelling.
What is the Iceberg Theory in Screenwriting?
Imagine an iceberg. Only a fraction of its mass is visible above the waterline; the vast majority is hidden beneath the surface. The Iceberg Theory suggests that in your screenplay, you should only present that visible fraction of information, dialogue, and character motivation. The hidden seven-eighths represents the rich, unspoken backstory, the complex internal lives of your characters, and the subtle subtext that the audience feels rather than explicitly sees or hears.
Why is this crucial for screenwriters?
- Engages the Audience: Audiences are intelligent. They love to connect the dots, interpret nuances, and actively participate in the storytelling. By omitting explicit details, you invite them to lean in, ponder, and form their own conclusions, making the experience far more immersive and satisfying.
- Creates Depth and Realism: Life isn’t a series of exposition dumps. People don’t always say exactly what they mean, and their actions are often driven by unspoken desires, fears, and histories. The Iceberg Theory allows you to build characters and situations that feel authentic and multi-layered, mirroring the complexities of real life.
- Enhances Subtext: Subtext is the beating heart of great screenwriting. It’s what’s really going on beneath the surface of the dialogue and action. When you embrace the Iceberg Theory, you naturally lean into subtext, allowing it to add tension, irony, and emotional resonance to every scene.
- Avoids On-the-Nose Writing: No one wants to be spoon-fed information. Overt exposition, clunky dialogue explaining a character’s entire past, or heavy-handed thematic statements can quickly disengage an audience. The Iceberg Theory helps you avoid these pitfalls, trusting your audience to understand without being told directly.
How to Apply the Iceberg Theory in Your Screenplay:
- Know Your Characters Inside Out: Before you can omit, you must know. Develop extensive backstories for your characters – their childhoods, their triumphs, their traumas, their deepest desires. Even if only 10% of this information makes it to the screen, that 10% will be imbued with the weight and authenticity of the unseen 90%.
- Dialogue with Purpose and Subtext: Every line of dialogue should serve multiple purposes. What is the character saying? What are they not saying? What do they really mean? Consider how a character’s past might influence their word choice, their tone, or their silences.
- Show, Don’t Tell… and Then Omit More: Instead of describing a character’s grief, show them staring blankly at a wall, a single framed photo the only indicator of their loss. Instead of having a character say they’re angry, show them clenching their jaw, their knuckles white. Then, ask yourself: what else can I remove while still conveying the essential truth?
- Leverage Visual Storytelling: Cinema is a visual medium. Use production design, costumes, props, and blocking to hint at deeper meanings and backstories without needing a single line of dialogue. A faded tattoo, a worn photograph, a particular way a character holds themselves – these are all parts of the visible iceberg that suggest a vast, unseen world beneath.
- Trust Your Audience: This is perhaps the most important aspect of the Iceberg Theory. Have faith that your audience is smart enough to pick up on subtle cues and draw their own conclusions. Resist the urge to over-explain.
The Power of What’s Unsaid
The Iceberg Theory is a masterclass in the power of suggestion. It’s about crafting a narrative that feels rich and profound because of its carefully considered omissions. It allows for ambiguity, nuance, and a deeper emotional connection between your story and your audience.
So, the next time you’re writing, remember Hemingway’s iceberg. Focus on the visible eighth, but ensure that the unseen seven-eighths is so robust and well-developed in your own mind that its presence is powerfully felt, even when it’s never explicitly stated. Your screenplay will be all the stronger, and your audience all the more captivated, for it.
