Why This Matters

When you're analyzing film for this course, you're not just watching stories unfold—you're dissecting how writers construct characters that feel alive. Every memorable protagonist, every chilling antagonist, every scene-stealing supporting player exists because of deliberate craft choices. You're being tested on your ability to identify these techniques, explain why they work, and apply them in your own writing.

Character development connects directly to larger course concepts: narrative structure, theme development, audience engagement, and visual storytelling. The elements below aren't isolated tricks—they work together as an interconnected system. A character's flaw creates conflict, which shapes their arc, which reinforces theme. Don't just memorize definitions—know what storytelling problem each element solves and how it functions within the larger screenplay architecture.


The Engine: What Drives Characters Forward

Every compelling character needs something propelling them through the story. These elements answer the fundamental question: why does this character act?

Motivation

  • The "why" behind every choice—motivation is the engine that makes character behavior feel logical and inevitable rather than random
  • Can stem from desire, fear, or external pressure—the best motivations tap into universal human experiences that audiences recognize in themselves
  • Creates story causality—when motivation is clear, each scene connects to the next through character-driven logic, not coincidence

Goals and Desires

  • Define the concrete objective—goals give motivation a tangible target (what does the character want in this scene, this act, this story?)
  • Operate on multiple timescales—short-term objectives (survive this conversation) and long-term aspirations (find belonging) create layered tension
  • Must evolve to show growth—static goals suggest static characters; shifting desires signal transformation

Compare: Motivation vs. Goals—motivation is the why (revenge, love, survival), while goals are the what (kill the antagonist, win the partner, escape the island). An FRQ might ask you to distinguish between these: motivation is internal and emotional, goals are external and actionable.


The Journey: How Characters Transform

Character arcs are what separate flat figures from dimensional people. These elements track change over time—the transformation that gives stories emotional resonance.

Character Arc

  • The transformation trajectory—arcs map how a character changes (or pointedly refuses to change) from beginning to end
  • Positive arcs show growth, negative arcs show declineMichael Corleone's descent is as valid as Luke Skywalker's rise; both create meaning
  • Drives audience satisfaction—viewers invest in characters because they want to witness change; arcs deliver on that promise

Backstory

  • Provides causal context—backstory explains how a character became who they are, making present behavior feel earned rather than arbitrary
  • Should be revealed strategically—drip information to maintain mystery; avoid exposition dumps that halt momentum
  • Functions as hidden motivation—the best backstories create subtext; characters act on wounds they may not even consciously acknowledge

Compare: Arc vs. Backstory—backstory looks backward (what happened before), arc looks forward (what's happening now and where it leads). Strong screenwriting connects them: backstory creates the wound, arc depicts the healing (or deepening) of that wound.


The Obstacle: What Creates Dramatic Tension

Conflict is the lifeblood of drama. Without resistance, characters have nothing to push against—and audiences have nothing to watch.

Internal and External Conflicts

  • Internal conflict is the battle within—moral dilemmas, emotional struggles, competing desires (should I betray my friend to save myself?)
  • External conflict comes from outside forces—antagonists, institutions, nature, society pressing against the character's goals
  • Both types must intersect—the strongest stories make external obstacles trigger internal reckonings; the external fight mirrors the internal one

Flaws and Weaknesses

  • Create relatability through imperfection—flawless characters feel alien; flaws make characters human and worthy of empathy
  • Generate conflict organically—a character's pride, fear, or blind spot becomes the source of their problems, not just external bad luck
  • Must balance with strengths—flaws without competence creates a victim; strengths without flaws creates a bore

Compare: Internal Conflict vs. Flaws—a flaw is a trait (arrogance, cowardice), while internal conflict is the struggle that flaw produces (choosing between self-preservation and doing the right thing). Flaws are static descriptions; internal conflicts are active dramatic processes.


The Surface: How Characters Are Expressed

These elements are how audiences actually perceive character—the external manifestations of internal reality.

Dialogue and Voice

  • Reveals character through speech patterns—word choice, rhythm, and vocabulary signal education, region, emotional state, and worldview
  • Must be distinct per character—if you can swap dialogue between characters without noticing, the voices aren't differentiated enough
  • Serves multiple functions simultaneously—strong dialogue advances plot, reveals character, and develops relationships all at once

Physical Appearance and Mannerisms

  • Visual shorthand for internal traits—costume, posture, and gesture communicate character before a single line is spoken
  • Mannerisms reveal emotional subtext—a nervous habit, a distinctive walk, a way of avoiding eye contact tells audiences what characters won't say
  • Should align with (or deliberately contradict) personality—a gentle giant or a well-dressed villain uses appearance to create productive tension

Personality Traits

  • The consistent behavioral patterns—traits define how a character typically responds to situations (optimistic, suspicious, impulsive)
  • Require both strengths and weaknesses—complexity comes from contradiction; a brave character who's also reckless feels real
  • Must allow for growth—traits should be consistent enough to be recognizable but flexible enough to evolve through the arc

Compare: Dialogue vs. Mannerisms—both reveal character, but dialogue is verbal expression while mannerisms are physical expression. In visual storytelling, mannerisms often carry more weight because film is a visual medium. If an FRQ asks about "showing vs. telling," mannerisms are showing; dialogue risks telling.


The Web: How Characters Connect

Characters don't exist in isolation. Relationships create the social fabric that tests, reveals, and transforms them.

Relationships with Other Characters

  • Function as mirrors and catalysts—other characters reflect hidden aspects of the protagonist and force them to confront truths they'd avoid alone
  • Reveal different facets of personality—how a character treats a subordinate vs. a superior vs. a love interest shows their full dimensionality
  • Can be supportive, antagonistic, or complex—the richest relationships resist easy categorization; allies who challenge and enemies who understand create depth

Compare: Relationships vs. External Conflict—not all relationships are conflicts, and not all external conflicts are relational. A hurricane is external conflict but not a relationship; a supportive mentor is a relationship but not a conflict. However, the most dramatically potent relationships contain conflict—tension between characters who need each other.

Self-Check Questions

  1. What's the difference between a character's motivation and their goals? Identify a film character and distinguish between the two for that character.

  2. Which two elements work together to create the "wound and healing" pattern in character development? How do they connect?

  3. If an FRQ asked you to analyze how a film "shows rather than tells" character, which elements would you focus on and why?

  4. Compare and contrast internal conflict and flaws—how are they related, and what makes them distinct concepts?

  5. A character has clear goals, distinctive dialogue, and memorable mannerisms, but audiences find them flat and unengaging. Which elements are likely missing or underdeveloped? Explain your reasoning.
