How to Write Conflict: The Three Types Every Scene Needs

Here is the working definition I use after fifteen years in the cutting room: conflict is what a character wants crashing into what stands in the way. No want, no obstacle, no conflict. No conflict, no scene. That is the whole subject of how to write conflict, and it comes in exactly three types. Learn to tell them apart and every flat scene you have ever written gets a diagnosis.

The subway scene that runs on almost nothing

In Joker, there is a scene on a subway where Arthur Fleck gets harassed by three drunk Wayne employees and ends up shooting them. Here is what makes it worth studying: Arthur has no plot goal in this scene. He is not trying to get something from anyone or get anywhere. He is just riding the train. A film analyst I follow once noted that the reason plot and strong character goals matter is that they are the thing that creates conflict and situations, and then pointed out that this scene should not work, because Arthur wants nothing here.

It works because the conflict is internal, and it has been building for an hour. Arthur's uncontrollable laughing condition fires whenever he feels unsafe, which means his own body betrays him at the worst moments. He wants to disappear. The world will not let him. The three men are just the spark; the real collision is between the man Arthur is trying to be, quiet, invisible, harmless, and the man the world keeps forcing him to become, the same machinery that keeps a flawed protagonist sympathetic. When he finally pulls the trigger, the shock is not that he shot them. The shock, for the audience, is that it took him this long.

That is internal conflict: the character versus themselves. Their fear against their desire. Their nature against their situation. It is the quietest of the three types and the hardest to fake, because you cannot stage it with props. It has to be written into who the person is.

How to write conflict: name the type, then sharpen it

Most weak scenes are not missing conflict. They are missing a clear type of it, so the collision stays blurry. The three types:

Internal: the character versus themselves. A want at war with a fear, a belief, or a condition. Joker's Arthur wants to be left alone and loved in equal measure, and his own mind will not let him have either. Internal conflict is what makes an audience lean forward in a quiet room.

Interpersonal: the character versus another person. Two wants, one space, no compromise available. This is the engine of most great scenes because it plays out in dialogue and action, right in front of the camera.

External: the character versus the world. Nature, war, machines, systems, anything bigger than any person in the frame. This is the type beginners reach for first and rely on most, which is exactly why it fails most.

The types stack. The best scenes run two or three at once. But each type has its own rules, and the proof is on screen.

One film per type, with the scene to steal

Interpersonal, proven: Deadpool and Wolverine. This entire film is a masterclass in manufacturing interpersonal conflict before a word is written. Deadpool is the most unserious jokester in the multiverse; Wolverine is the most dead-serious grump in it. Put them in a room and the scenes write themselves: constant arguments, no pulled punches, two people who cannot coexist in harmony. As the breakdown I studied put it, differences mean gravitational pull and friction and eventual conflict. When two characters want opposite things, or want the same thing in opposite ways, every exchange becomes a small war. The payoff lands at the end precisely because they were opposites: two people who should never work together finding a way to do it anyway is one of the most rewarding emotions in film. If your scene has two characters who agree with each other, you do not have interpersonal conflict. You have a conversation. Fix it by giving them opposite wants.

External, proven (and warned about): Transformers: Age of Extinction. On paper, this film has enormous external conflict: the government is hunting the Transformers, a rogue agency is building its own robot army, the fate of the species is at stake. It should be gripping. It is not, and the reason is the lesson. The film's goofy tone turns every emotional beat into a joke, the hero's bond with Optimus Prime is never actually built (we never see him consider selling Optimus out for the reward and refuse, never see him choose loyalty over money), and so the world-ending stakes land on nothing. External conflict is a multiplier, not a foundation. Multiply zero personal stakes by a thousand robots and you still get zero. External spectacle without story is just noise. The rule: never write an external threat until you can answer what it costs this specific character, personally, today.

Internal, proven: Joker, once more. The film's famous laughing condition is worth stealing as a device, not a gimmick. It externalizes the internal: every time Arthur feels unsafe, his body announces it, which means his inner state is always colliding with his surroundings. You do not need a medical condition to do this. Give your character a belief that contradicts their goal (I want to be a comedian; I believe the world is laughing at me, not with me), and every scene becomes a battlefield they carry inside them.

Key points

• Conflict is a want crashing into an obstacle. No want, no scene.
• Internal conflict is character versus self: fear against desire. It holds quiet scenes.
• Interpersonal conflict is character versus character: two wants, one space. Opposites generate it automatically.
• External conflict is character versus world: war, nature, systems. It multiplies personal stakes but cannot replace them.
• The strongest scenes stack types: an argument (interpersonal) about a fear (internal) during a crisis (external).
• If a scene feels flat, name which type it is supposed to be, then check whether the want and the obstacle are both specific.

Try this

• Watch the subway scene in Joker and write down Arthur's internal want versus what his own body does to him. That gap is the scene.
• Take one flat scene from your script and rewrite it twice: once where the two characters want opposite things, once where the hero's fear fights their goal. Keep the stronger version.
• Watch any ten minutes of Transformers: Age of Extinction and notice how the external spectacle feels empty without a personal cost attached. Then attach one to your own set piece.
