Proven Steps for Writing Complex Characters in Screenplays

Writing complex characters is one of the biggest challenges we face as screenwriters and producers, especially with today’s standards demanding originality, depth, and authenticity.

It’s easy to get stuck with flat or familiar archetypes that stall your script’s progress.

We know how crucial it is to stand out, so we’ve created a practical guide that covers:

• Proven steps for writing complex characters that resonate and evolve
• Psychological models to add depth and surprising motivations
• Reliable feedback strategies to sharpen authenticity and market appeal

Understand What Makes a Character Complex

You want characters who leap off the page—compelling, real, never predictable. That’s non-negotiable for a script that stands out and gets a “yes.” Complexity goes farther than just listing a few traits. You’re building a person who evolves, reacts, contradicts, surprises, and lingers in the mind of every reader.

Hallmarks of Complex Characters

Here’s what sets a complex character apart from the crowd:

• Transformation drives story: Tony Stark shifts completely, turning arrogance into true sacrifice in “Avengers: Endgame.” Change hooks both industry readers and audiences.
• Contradiction sustains interest: Walter White inspires and unsettles as pride pulls him toward both care and cruelty.
• Archetypes with depth: Tony Soprano or Leia Organa live beyond their “role” through specific vulnerabilities and values.
• Organic evolution: The best characters make choices, face flaws, and are changed by high-stakes moments.

Industry coverage consistently knocks scripts with one-note or static roles. Executives, producers, and story analysts are trained to spot flat, forgettable personas immediately. You need to bring dimension, surprise, and emotional logic every time.

Dynamic, evolving characters anchor the script and define its quality.

Common Pitfalls to Watch For

The biggest misses we see in submissions:

• Characters “described,” never defined: If you rely on lists of quirks, readers check out early.
• Emotional ambiguity: Lack of clarity makes it tough for anyone to care about their journey.
• No growth: Audiences want to see someone fundamentally changed (positively or negatively) by the story.

Scripts that thrive on the market show authentic transformation and unpredictable depth. That’s the new standard.

Study the Psychology Behind Motivations and Behaviors

To make your characters unforgettable, you need to move past surface. Dive into real motivations, fears, value systems, and core desires. This is where screenwriting gets serious and stakes get real.

Leverage Models That Writers Trust

Professional writers pull from the latest behavioral science:

• Motivational systems: The SDI breaks motivation into three categories—Altruistic-Nurturing, Assertive-Directing, Analytic-Autonomising. Use this to reflect the conflicting value systems driving major players in “The Missing.”
• Layered personalities: Powerful arcs blend two or even all three motivational systems, building inner conflict. A mentor can be driven, compassionate, yet skeptical—giving every choice extra weight.
• Evolving drives: As the story escalates, watch how a nurturing figure becomes assertive or a self-confident leader faces sudden self-doubt. That’s where growth comes alive.

Bring Psychology Into Plot

• Internal beliefs and subconscious drivers change how your characters react. They fight, run, sabotage themselves—or step up when challenged.
• The more true-to-life the mix, the more natural your character’s logic feels, even when they surprise you.
• Layering aims, beliefs, and fears keeps the reader guessing and caring.

Your reader recognizes authenticity. When your characters’ choices arise naturally from layered motives, you show you understand the craft at the highest level.

Start With Purpose: Define Roles and Archetypes

Every character must serve a function. Purpose isn’t about typing—“mentor” or “villain”—it’s about clarity: What does this person do to the plot? Whose arc do they affect, and how?

Unleash the Power of Clear Roles

We always encourage writers to:

• Name roles fast: Tony Stark is the protagonist, Nebula is first an antagonist, then ally. No confusion.
• Subvert expectations: Take a “wise mentor” and expose flaws, or have an “antagonist” move from foe to ally like Nebula in “Guardians of the Galaxy: Volume 3.”
• Define personal stakes: Does your character’s action change the outcome, heighten danger, or force others to evolve?
• Lock roles to narrative: Mary Jane in “Spider-Man” defines both Peter’s emotional stakes and what’s worth risking as conflict deepens.

When roles are unclear or feel recycled, the script feels generic. But when you ground a character’s actions in clear personal and plot purpose, investment follows.

Roles set the stage, but only transformation wins the audience.

Build Backstory and Inner Conflict for Depth

You need to know what keeps your character up at night—years before your opening scene. A well-built backstory shapes every choice and mistake.

Craft Layered, Motivating History

• Paragraph mapping: Instead of laundry lists, use strong narrative paragraphs. Tony Soprano splits loyalties between crime and family. Faramir’s heartbreak colors his every risk.
• Micro-narratives: Short, focused events provide logic: Buzz Lightyear’s longing for purpose, or Hannibal Lecter’s mysterious hints at a terrifying past.
• Internal contradictions: Allow for strong, natural inner conflict. Walter White’s care for his family fuels his moral slide; Shrek’s bluster shields deep isolation.

Why Conflict Matters

When your character’s present behavior grows from real wounds, hopes, and failures, audiences believe it. The most chilling villains become unforgettable when their backstories explain both their menace and humanity. Flaws, fears, misbeliefs, and desires push every arc forward.

Scripts that seed and reveal backstory with intent keep attention high—and make emotional payoffs possible.

Develop Unique Traits, Flaws, and Contradictions

To raise your script above the crowd, your cast needs only-in-this-movie characteristics. The right details just stick.

Build Standout, Specific Details

• Contradictory traits: Give Gracie Hart (“Miss Congeniality”) toughness wrapped around vulnerability. Show Nebula’s loyalty flicker through anger.
• Signature flaws: Walter White’s pride drives his genius and descent. Make every flaw believable, seeded in the past, visible in the present.
• Unusual combinations: Create a leader who’s deeply insecure, or a villain with moments of kindness. Traits must clash—authentically—within your story’s world.
• Reference high-quality lists: Pull a trait or quirk from reputable sources like 350 Character Traits, but own it, twist it, make it fresh.

A character’s flaws should fuel mistakes, conflict, and growth. The Beloved Joker didn’t just break rules—he stood out with strange logic and unpredictable pain.

The fastest way to empathy: traits and contradictions that nobody else could write but you.

Let every character trait spark conflict or connection. If it could be swapped into a dozen other scripts without changing the story, it’s time to go deeper.

Make Choices Under Pressure: Reveal Character Through Action

True character appears under fire. The industry wants to see who your lead becomes at the breaking point, not just how they talk or move. Good scripts test beliefs, values, and relationships by forcing urgent, meaningful decisions.

Pressure Reveals Priorities

• Actions speak first: Tony Stark risks everything in his last stand. Mary Jane leaps toward risk for love instead of staying safe.
• Escalating dilemmas: Great characters face decisions between two values—save a friend, win the mission, or preserve their pride. That’s real suspense.
• Consistency vs. surprise: Readers connect when character choices feel earned, even if surprising. Tony Soprano’s actions sometimes crack his mobster image, but each twist makes internal sense.

Place every core character in at least one scene where they must choose. Each decision reveals what truly matters.

High-stakes choices are the heartbeat of a complex character arc.

Let actions trigger consequences. Conflict sharpens, bonds form or break, and your script stays gripping.

Workshop Characters Through Dialogue, Relationships, and Rewrites

Complexity isn’t perfected in the first draft. Dialogue, interaction, and repeated feedback shape the final result. Greenlight Coverage sees time after time that strong scripts undergo multiple rounds of evolution—especially when sharpening character voices.

Dialogue and Interaction: The Crucible

• Personalized language: Your hero, villain, and ally should never sound alike. Dialogue must come from unique goals, fears, and mindsets.
• Subtext over exposition: Trust sharp lines and emotional undercurrents. “Talking heads” drain momentum; intention-driven exchanges reveal character.
• Relationship-driven change: Buzz and Woody’s rivalry forces both to mature. Group dynamics, contrasting energies, and sharp conflicts all forge new layers.

Avoid Common Pitfalls When Writing Complex Characters

Most scripts fall flat because writers step into unseen traps. Condense years of industry insights with our rapid-fire assessment.

Pitfalls and Fix-It Steps

• Tropes, not twists: Swap out generic roles for subverted archetypes. Make every character unique.
• Backstory overload: Weave history through action, not heavy-handed flashbacks or dump-scenes.
• Vague motivations: Pin down concrete fears, desires, and wounds. Every move should make emotional sense.
• Inconsistency: Lay groundwork for any contradiction. Surprises must fit the established logic.

Keep a sharp eye for habits that dilute character impact. High-quality coverage highlights these issues before your audiences or execs do.
