Flashbacks act as a sort of Swiss army knife. You can use them in multiple ways — to foreshadow coming events, flesh out characters, and relay necessary backstory. That being said, you don’t want to overuse them. Too many flashbacks and you risk confusing your audience.
In this article, I’ll explore what a flashback is, when to use it, and how some films use them to great effect. Finally, I’ll offer you a Story Weapon that will help you create flashbacks that marry exposition to experience.
Learning how to write flashbacks in a screenplay allows you to reveal critical backstory while maintaining emotional tension and dramatic irony. See examples that help you measure your written jumps to the past serve as a “pressure valve” that deepens the audience’s experience.
What is a flashback?
A flashback is just that: a scene that interrupts the story’s present timeline and “flashes back” to a previous point in one or more characters’ past.
Flashbacks can include a quick image, an entire scene, or even a full act of the script. Perhaps a character in your story suddenly remembers an event from their childhood, or the audience is shown an image that provides context for something the protagonist will encounter later.
When to use flashbacks
If you want to write a flashback in your screenplay, there are some things to consider.
1. Does it reveal new information to recontextualize something?
Every scene in your screenplay should advance the story in some way. A flashback allows you the opportunity to recontextualize what’s already occurred.
For example, a cruel villain might be shown instead as a tormented victim in a scene showing their original turning point.
2. Is there no better way to convey the event?
Emotion is the keyword here. Showing something happening will have a greater impact on your audience than a character simply describing an event, but you don’t want to overdo it.
A flashback earns its place when it raises the emotional stakes. Your character has reached a breaking point, or they have to make an impossible choice, or confront something they’ve spent the whole story running from. That’s when the past stops being backstory and becomes the story.
Think of it as a pressure valve. The present scene builds tension to the point where the audience needs to understand why this moment carries so much weight. The flashback technically interrupts the scene, but it doesn’t interrupt that tension. It deepens it.
3. Does the flashback give answers or generate more questions?
The best flashbacks can do both. A flashback can provide the context your audience needs to understand why your protagonist behaves the way they do in the present — the wound that explains the limp, so to speak. But a well-constructed flashback doesn’t just close a door; it opens a window onto something the audience didn’t know they needed to see. It answers the question of where your character came from while quietly planting the seeds of where they’re going.
Think of the flashback as a form of dramatic irony. When your audience is given a glimpse of the past that the characters don’t have access to, they begin to see the present story through a different lens. They understand something your protagonist may not yet understand about themselves. The gap between what the audience knows and what the character knows is where suspense lives.
A flashback that reveals a childhood betrayal, for instance, doesn’t just explain a character’s deep distrust of everyone around them in the present. It foreshadows a moment when that distrust will either save them or destroy them. The past isn’t just context — it’s a loaded gun. And if you’ve shown it to your audience early enough, they’ll spend the rest of the story waiting for it to go off.
Effective flashbacks
Let’s look at some movie examples that use flashbacks in different but effective manners. Spoiler warning if you haven’t seen these films yet!
Reservoir Dogs (1992)
There are many eccentric characters in Reservoir Dogs. There are hints of their character traits and personalities shown in their introductions. It’s during the flashback sequences, however, that we truly get to explore who these characters really are. Their loyalties, their worries, and even their flaws.
The numerous flashback sequences bring us out of the warehouse most of the movie takes place in, and allows us to gather puzzle pieces to see how these characters arrived in this situation. Ultimately, the flashbacks aren’t just fleshing out characters for the sake of building endearment, it’s building them up to further enhance the tension.
On one hand, the decisions of many characters in the future are “spoiled” by what the flashbacks show. But that itself shows how flashbacks are useful tools in allowing your story to round itself out.
If the iconic stand off at the end of the film didn’t come with the previous revelation of who the traitor is and just how loyal Mr. White was, then the impact wouldn’t reach the same height.
Blade Runner 2049 (2017)
As opposed to the drawn out flashback sequences in the previous example, Blade Runner 2049 features very brief jumps to the past. Nonetheless, there’s a lot to unpack there.
The flashback is cryptic, but loud. The revelation of the date 6/10/21 along with a blink-and-you’ll-miss-it flashback of a boy holding a wooden horse. It’s narrative smoke, signalling the start of the fire that is the plot at large.
Later on, we revisit the flashback again as K recounts a memory that he knows isn’t real. This then builds on a slowly developing mystery. The date 6/10/21 is actually written on that very same wooden horse. Now, the flashback acts as a natural bridge, bringing the story forward as K sets out to visit that place in his memory and uncover the truth.
The truth is that the flashback was wrong from the start. K really is just another replicant with no real significance in the past. The flashback in this case is one visited through an unreliable memory. This is yet another way to maximize the usefulness of flashbacks in your screenplay.
Manchester by the Sea (2016)
This film is told in a non-linear fashion with several flashbacks, but the key to the protagonist’s mindset and behavior is delayed. Lee Chandler is a man who is clearly broken. He is sullen, withdrawn, and carries a burden from his past.
By the time we’re given the central flashback and learn how Lee’s three children died in a house fire, the audience has spent enough time with Lee to feel the full force of what it reveals. We experience it the way Lee does, as something that can never be undone. The timing is everything. Had the same information been delivered in the opening scene, it would have been tragic. Arriving when it does, however, it becomes devastating.
A flashback is not just a way to deliver information. It is a way to control when your audience is ready to receive it.
Lee’s inability to forgive himself is something we sense long before we understand it. When the flashback finally reveals what happened, it locks the tension in place.
Your story weapon: Connecting exposition to experience
Screenwriters sometimes think flashbacks are simply a way to convey exposition. It’s a reasonable assumption, as flashbacks are a quick solution to keep the story moving.
But as a screenwriter, your job is not simply to advance the narrative, but to create a story that builds in meaning as it progresses. Your audience wants to experience the story — they don’t just want it explained to them. When a flashback is used well, it not only fills in the blanks on a plot level, it allows us an emotional experience by offering a glimpse into the character’s inner state or psyche.
With backstory, you are painting a picture with every line in your screenplay. A flashback allows you to take a step back and see the corners that were previously inaccessible.
