Character Development

Character development is the process of creating a fictional person who feels real, specific, and dramatically alive. It is the art and craft of deciding who a character is, what they want, why they behave the way they do, and how they will change over the course of the story.

Strong character development separates memorable screenplays from forgettable ones. Audiences may forget plot details within days of watching a film, but they remember characters for years — Hannibal Lecter's calm menace, Forrest Gump's sincerity, Ellen Ripley's toughness, the Dude's aimless charm.

The Foundations of Character

Every well-developed character rests on a set of foundational questions. Before writing a single scene, you should be able to answer the following about each major character:

What Do They Want?

The external goal is what the character is actively pursuing in the story. It should be specific, achievable, and urgently desired. "Wants to be happy" is too vague. "Wants to win the state championship to prove to his father that he is not a failure" is specific and dramatically charged.

What Do They Need?

The internal need is the deeper truth the character must confront or accept in order to grow. The character is usually unaware of this need at the beginning of the story. The tension between what they want and what they need creates the internal conflict that powers the character arc.

In Up (2009), Carl wants to keep his house — but he needs to let go of the past and embrace new relationships. His journey from wanting to needing is the film's emotional spine.

What Is Their Flaw?

A character flaw is a weakness, false belief, or destructive pattern that prevents the character from achieving their need. Flaws are not necessarily moral failings — they can be fears, insecurities, blind spots, or deeply ingrained habits.

Without a flaw, a character faces no internal resistance. Without internal resistance, there is no character arc.

What Is Their Backstory?

Backstory is everything that happened to the character before page one of the screenplay. It shapes who they are when the story begins — their worldview, their relationships, their fears, and their default behaviors.

Not all backstory needs to appear on screen. But the writer must know it, because it informs every choice the character makes.

What Is Their Voice?

A character's voice is their distinct way of expressing themselves — their vocabulary, sentence structure, sense of humor, emotional register, and the gap between what they say and what they mean.

Voice is what makes dialogue feel like it belongs to a specific person rather than a generic mouthpiece. In The Big Lebowski (1998), the Dude's voice — rambling, laid-back, peppered with "man" and "like" — is so specific that you could identify his lines without attribution.

Techniques for Developing Characters

The Character Interview

Write a question-and-answer session with your character. Ask them about their childhood, their greatest fear, their most embarrassing moment, their opinion on love. Answer in their voice. This exercise surfaces details you might not discover through outline work alone.

The Object Exercise

Choose three objects in your character's home. Why do they own each one? What does each object reveal about them? A worn copy of a particular book, a photograph face-down on a dresser, a kitchen that is either spotless or chaotic — objects tell stories.

The Contradiction Method

Real people are full of contradictions. A tough cop who cries at dog commercials. A ruthless executive who is a devoted parent. An optimist who cannot commit to a relationship. Find the contradiction in your character — it will make them feel human.

The "Why" Chain

Start with a character behavior and ask "why?" five times:

1. "He refuses to ask for help." — Why?
2. "Because he was punished for showing weakness as a child." — Why?
3. "Because his father believed vulnerability was a character failing." — Why?
4. "Because his father grew up in poverty and learned that only self-reliance survives." — Why?
5. "Because three generations of loss taught the family that depending on others leads to betrayal."

Each "why" deepens the character and reveals the roots of their behavior.

The Mirror Test

Hold your character up to the themes of your story. Does the character embody, challenge, or complicate the theme? A story about forgiveness should feature a character who struggles to forgive — not one who forgives easily.

Developing Characters Through the Story

Character development is not just preparation — it happens during the writing. As you draft scenes, pay attention to:

• How the character reacts under pressure — stress reveals true nature
• What choices they make when options are limited — choices define character
• How they treat people with less power — this reveals morality
• What they do when no one is watching — private behavior exposes truth

The best character moments are often ones you did not plan — they emerge when you place a well-developed character in a difficult scene and write honestly about what they would do.

Frequently Asked Questions

How much backstory should I reveal in the screenplay?

Only what the audience needs to understand the character's present behavior. Backstory should be distributed sparingly — through dialogue, behavior, and visual details — rather than delivered in exposition dumps. Trust the audience to infer.

What if my character changes as I write?

That is usually a good sign. It means the character is becoming real enough to push back against your original plan. When a character "takes on a life of their own," it often means you have developed them deeply enough that their behavior has its own internal logic.

Should all characters be likable?

No. Characters should be compelling, not necessarily likable. Tony Soprano, Amy Dunne, and Daniel Plainview are deeply unlikable — and endlessly watchable. What matters is that the audience understands why the character does what they do, even if they disagree.

How do I develop a character who is very different from me?

Research and empathy. Read about people who share the character's background, profession, or experiences. Interview them if possible. Watch documentaries. The goal is not to become the character but to understand their worldview well enough to write them honestly.
