Backstory

In practice

Backstory is the life a character lived before page one. It includes where they grew up, who raised them, what they lost, what they did that they regret and what they still believe because of it. None of it happens on screen, but all of it shapes how the character behaves in every scene that does.

The most useful part of a backstory is usually a single event that still hurts. Screenwriting teachers give it different names: John Truby calls it the ghost, Michael Hauge the wound. It explains the character's fear, their defenses and the mistaken belief they carry into the story, which the plot will force them to confront. A strong backstory is less a biography than a reason.

Writers often know far more backstory than they ever put in the script. That knowledge makes the character consistent and specific, but on the page, backstory works best in small doses revealed under pressure. When a detail from the past arrives at the moment it changes what a character does, the audience feels the history instead of being told about it.

The scene never says what happened to Alvarez. The helmet, Tess's hands and the way she closes the locker let the audience infer a loss and her guilt about it. That inference does more than an explanation would, and it leaves the full story to be revealed later, when it can change a decision.

Backstory, the ghost and the wound

Backstory is the broad history of a character, much of which may never appear in the script. Within it, writers look for the event that still drives the character in the present. John Truby's The Anatomy of Story calls it the ghost, something from the past that haunts the hero, while Michael Hauge calls it the wound: an unhealed hurt that creates the fear the hero must overcome.

The wound usually produces a false belief. A character abandoned as a child may believe that anyone they love will leave, and so they keep everyone at a distance. That belief is what the character arc will challenge. Knowing the backstory event lets you dramatize the belief clearly, and lets the climax show the character finally acting against it.

Backstory is not the same as exposition. Backstory is the content, what happened before; exposition is the technique of delivering any necessary information to the audience. Bad exposition dumps backstory in a speech nobody would really give. Good exposition hides it inside conflict, so that the past surfaces because one character wants something from another.

Backstory in well-known films

In Casablanca, Rick Blaine's bitterness is a mystery until Ilsa walks into his café. The film withholds their past in Paris until the middle of the story, then shows it in a flashback, and from that point every exchange between them carries the weight of what they lost. The backstory explains Rick's cynicism and sets up the sacrifice he makes at the end.

In Jaws, Quint's monologue about the USS Indianapolis is backstory delivered at exactly the right moment. Drunk and swapping scars with Hooper and Brody, he describes surviving the 1945 sinking while sharks killed hundreds of men in the water. The speech explains his obsession with the shark and raises the dread just before the creature returns.

Up does the opposite and puts its central backstory at the very beginning. A wordless sequence shows Carl and Ellie's life together, from childhood to her death, including the adventure they always meant to take. Everything Carl does afterward, from refusing to sell the house to tying it to balloons, comes from that backstory, and the audience understands it without a word of explanation.

How to write backstory in a screenplay

Know more than you show. Many writers draft a short history for each main character, covering family, formative events, the wound and the belief it created. Very little of it goes into the script, but it lets you answer any question about how the character would react, and it keeps their behavior consistent from scene to scene.

Reveal backstory under pressure and only when it's needed. The best moment to reveal a piece of the past is when it changes what's happening now, such as explaining a choice, shifting a relationship or raising the stakes. Information the audience doesn't need yet can wait, and holding it back creates curiosity that keeps them watching.

Avoid as-you-know dialogue, where characters tell each other things they both already know so that the audience can hear them. Show the effects of the past instead: a habit, a scar, an object, a reaction that seems too strong. Use flashbacks sparingly, and only when the past moment is dramatic in itself, not simply informative.
