Backstory
The history of a character or world that occurred before the story begins, shaping present behaviour and conflict.
Backstory
noun | Screenwriting & Development
The history of a character, relationship, or world that predates the beginning of the film and whose consequences shape the present action of the story. Backstory is the accumulated past that the characters carry into the narrative - the wounds they have not healed, the relationships that were broken, the decisions that cannot be undone. The audience rarely sees backstory directly; they feel its effects through the characters' present behaviour, choices, and emotional responses.

The Explanation: How & Why
Backstory is what makes characters dimensional. A character with no history is a function - they exist to perform a narrative role. A character with a rich, specific, coherent backstory is a person - they have been shaped by experience, carry the weight of the past, and respond to present situations in ways that reflect who they have been as well as who they currently are.
The most important principle of backstory is that the writer needs to know it even when the audience does not. A writer who does not know their protagonist's history cannot write them consistently - the character's emotional responses will be arbitrary rather than rooted. A writer who knows exactly what happened to their protagonist ten years before the film begins writes every scene with that knowledge informing the character's behaviour, even when it is never explicitly stated.
How much backstory to reveal is a critical screenwriting decision. Several principles govern it:
Reveal what the present story requires. If the protagonist's backstory is not relevant to the present conflict, it does not need to be in the film. The writer knows it; the audience does not need to. Backstory for its own sake is exposition for its own sake - dead weight in the narrative.
Reveal backstory at the moment of maximum impact. A piece of backstory delivered in the first act as neutral information produces a very different effect than the same backstory revealed in the third act as a dramatic revelation. Timing is everything. The best backstory revelations are the moments when previously incomprehensible character behaviour suddenly becomes completely understandable.
Let behaviour carry backstory. The most elegant backstory delivery is not expository at all - it is behavioural. A character who cannot enter a room without checking the exits, who flinches at a specific kind of touch, who refuses a specific kind of offer - the audience infers the history from the behaviour without being told it. The backstory is present in the character's body and choices without being stated. As scriptstrategy.com notes, the best screenwriters weave backstory into the fabric of a scene, often without a single word of explanation.
Historical Context & Origin
The concept of backstory in dramatic writing is ancient - Greek tragedy built entire plots around the consequences of events that occurred before the play began. Oedipus's backstory is the entire substance of Oedipus Rex; the play is the protagonist discovering what the audience already knows. In modern screenwriting pedagogy, backstory became a formal analytical category through the work of screenwriting educators in the 1970s and 1980s who codified the structure of character development. Syd Field's Screenplay (1979) and Robert McKee's Story (1997) both emphasised the importance of the writer's complete knowledge of a character's history as the foundation of believable characterisation, establishing backstory as a fundamental concept in the vocabulary of professional screenwriting.
How It's Used in Practice
Scenario 1 - Character Development (Screenwriter): A screenwriter writing a war film protagonist documents five pages of the character's backstory before writing a single scene: family of origin, formative relationships, the specific incident that shaped their relationship to violence, the loss that defined their adult life. None of this information appears directly in the 110-page script. But every scene the character plays is written with this history in the writer's mind, and the character's responses feel rooted and consistent as a result.
Scenario 2 - Delayed Revelation (Director / Screenwriter): A mystery drama withholds the protagonist's backstory for two acts. The audience knows she is guarded, precise, and inexplicably afraid of water. In the third act, a single scene reveals the backstory: a childhood drowning incident in which she failed to save her younger brother. Every behaviour from the previous two acts suddenly becomes completely legible. The delayed backstory revelation is the film's emotional climax.
Scenario 3 - Subtext Backstory (Director / Actor): An actor playing a character whose alcoholism is backstory - not current action in the film - discusses the character's history with the director before filming. The character has been sober for five years, and there are no scenes of drinking. But the actor plays every social situation with a specific quality of vigilance - always knowing where the exit is, never fully at ease - that communicates the history without stating it. The backstory lives in the performance.
Usage Examples in Sentences
"The writer needs to know the backstory even when the audience never learns it. The history shapes the behaviour."
"Do not tell me the backstory in the first act as neutral information - save it and make it a revelation in the third."
"The character's specific way of holding themselves in a crowd is the backstory. No dialogue required."
"Every behavioural detail that feels unexplained is backstory waiting to be revealed or not revealed."
Common Confusions & Misuse
Backstory vs. Exposition: All backstory is a form of exposition - information about the past. But exposition is broader, covering any background information the audience needs to understand the story's present circumstances, including world-building details, organisational structures, and geographical context that have no specific character history dimension. Backstory specifically concerns the history of characters and relationships before the story began.
Backstory vs. Flashback: A flashback is a structural device - a scene or sequence dramatising past events. Backstory is the content - the events themselves. Backstory can be delivered through flashback, but it can also be delivered through dialogue, behaviour, visual detail, or subtext without any flashback structure. Not all backstory requires flashback; not all flashbacks contain backstory (a flashback can dramatise events from earlier in the present story rather than pre-story history).
Backstory vs. Character Bio: A character bio is a writing tool - a document the writer creates for themselves, often running 5 to 15 pages, covering the character's full life history. Backstory is the narrative concept - the subset of that history that shapes the present story. A writer may create a 20-page character bio but only 3 pages of it become backstory relevant to the film.
Variations by Context
| Context | How the Term Varies |
|---|---|
| Feature Screenplay | Backstory is typically revealed through dialogue, behaviour, and at most 1 to 2 flashbacks across a 90 to 120 page script. The writer documents full character bios during development but drips backstory into the narrative only when the present story demands it. |
| Television | Backstory unfolds across multiple episodes and seasons. A showrunner may hold backstory elements in reserve for future seasons, revealing them gradually. Character backstories in TV are more extensive because the format allows long-term revelation. |
| Independent / Low Budget | Backstory delivery is often behavioural rather than visual because flashbacks require additional shooting days, locations, and cast. Budget constraints push writers toward subtext-driven backstory. |
| Novel Adaptation | Novels contain extensive backstory that must be cut or condensed for the screen. The adapter's job is to identify which backstory elements the present story requires and discard the rest, even when the novel's fans expect it. |
Key People & Films
Manchester by the Sea (2016), written and directed by Kenneth Lonergan, is a masterclass in behavioural backstory: Lee Chandler's past is revealed through his present isolation and emotional shutdown long before the specific tragedy is disclosed. Moonlight (2016), directed by Barry Jenkins, uses visual metaphor - the ocean, the bathtub - to carry Chiron's backstory without exposition. Casey Affleck's performance in Manchester by the Sea and Mahershala Ali's in Moonlight demonstrate how actors embody backstory through physical behaviour. Good Will Hunting (1997), written by Matt Damon and Ben Affleck, targets a specific backstory element - childhood abuse - that directly informs the protagonist's fatal flaw, following the principle that backstory should serve the present story's emotional logic.
Equipment / Tools Reference
Screenwriters document backstory in Final Draft using the Character Beat or ScriptNotes features to track character history alongside the script. WriterDuet offers character profiles and outline modes for organising backstory before drafting. Highland 2 provides a Character sidebar where writers store bios and backstory notes. Save the Cat! software includes a Board feature for mapping beats that carry backstory. Physical index cards and notebooks remain common among writers who prefer tactile organisation during the development phase.
Standards & Specifications
The WGA (Writers Guild of America) does not prescribe a specific format for backstory documentation - it is a development tool, not a deliverable. However, the WGA Format Guide governs how flashback scenes (a common backstory delivery method) are formatted in a screenplay: slug line begins with "FLASHBACK" or "INTERCUT" with a past-tense scene description. Standard industry practice for character bios in development documents runs 5 to 15 pages for a feature protagonist, 2 to 5 pages for supporting characters. Studio development departments typically require character bios as part of the development package before greenlight.
Common Questions / FAQ
Q: How much backstory should I write before starting the script?
A: Most working screenwriters document 5 to 15 pages of character backstory for a protagonist before drafting. The key is knowing the character's history well enough that every scene feels rooted. However, only the backstory elements that directly affect the present story should appear in the script itself.
Q: Should I use a flashback to reveal backstory?
A: Only when the backstory revelation creates a dramatic effect that dialogue or behaviour cannot achieve. Flashbacks interrupt the present narrative. If a character's history can be shown through their current behaviour - flinching, avoiding, overcompensating - that is almost always stronger than cutting to the past. Save flashbacks for moments when the audience needs to see the formative event to understand the present climax.
Q: What is the difference between backstory and a character bio?
A: A character bio is the writer's private document covering the character's full life. Backstory is the narrative concept - the elements of that history that shape the present story. You may write a 20-page bio but only 3 pages of it become backstory relevant to the film.
