Two kinds of pressure on a character
External conflict is the opposition a character encounters in the world of the story. A rival wants the same job. A storm blocks the road. A deadline forces a decision. These obstacles give a screenplay visible action: someone tries to achieve a goal, meets resistance and must change tactics. The external problem is often easy to state as a question: Can the protagonist get the evidence to the right person before it disappears?
Internal conflict is a struggle within the character. They may want trust but fear dependence, or value honesty while being tempted to conceal a mistake. It is not simply a feeling or a secret backstory. It becomes conflict when competing needs, beliefs or impulses make a choice difficult. A character who is frightened but has no reason to act differently may have an emotion; a character who must choose between safety and loyalty has a dramatic problem.
The distinction is useful, but it is not a rule that every story needs two separate plots. In an effective screenplay, the external obstacle can put pressure on the character’s inner contradiction. What happens in the world asks them to reveal who they are through what they do.
Give the outward goal a personal cost
Imagine a night-shift projectionist trying to save the only playable print for a small cinema’s final screening. The external goal is concrete: find and repair the print before the audience arrives. A broken reel, a locked storage room and a colleague with a different plan could all stand in the way. Those complications can keep the story moving, but on their own they may amount to a series of chores.
Now give the projectionist a habit of refusing help because they believe mistakes make them unworthy of trust. The same obstacles gain another dimension. Asking the colleague for the key is no longer a simple solution; it means admitting they cannot do everything alone. Hiding damage to the print might buy time but threaten the screening. The outward task repeatedly creates choices that test the inward belief.
When developing a protagonist, try writing two short sentences: “They are trying to…” and “They struggle to…”. The first should describe an objective that other characters could recognize. The second should describe a pattern that complicates their pursuit of it. If the sentences have no effect on each other, look for an external obstacle that forces the internal struggle into play.
Make internal conflict filmable
A screenplay cannot rely on an explanation of a character’s thoughts to carry every emotional turn. Internal conflict becomes legible through behavior, especially when a character has plausible alternatives. The projectionist might start to call a colleague, stop before the phone rings and attempt a risky repair alone. Later, they might finally hand over the damaged reel. Neither action needs to announce the character’s fear of dependence; the contrast between the choices can show it.
Dialogue can help when it also does something in the scene. A character may insist that everything is under control while their hands reveal otherwise, or argue over a practical plan while avoiding the admission they most need to make. Surrounding characters need not diagnose the protagonist. They can pursue their own goals, making the protagonist’s usual approach harder to maintain.
Be careful not to mistake repeated hesitation for development. If each scene only shows the character worrying, the story may feel stalled. Let an internal struggle affect tactics and consequences: they conceal information, lose an ally, change course or accept help at a cost. That way, the audience can track the struggle without needing access to the character’s private thoughts.
Build toward a choice that joins the conflicts
A strong turning point often makes the external goal harder to reach by the character’s familiar method. The projectionist can no longer fix the print alone. They might protect their pride and risk losing the screening, or tell the colleague what happened and work together. The practical problem has not vanished; it has become the occasion for a revealing decision.
That decision does not have to produce a tidy transformation. A character can change imperfectly, resist change or make the wrong choice. What matters is that the outcome follows from pressures the screenplay has established. If the climax resolves the external problem through a coincidence, the inner struggle may feel irrelevant. If it resolves only in a speech, the story’s visible action may feel unfinished.
As you revise, look at each major scene and ask what the character wants, what blocks them and what their response reveals. Then look at the ending: does the final choice answer both the practical question and the personal one? When external and internal conflict work together, the plot does more than keep a character busy. It gives every attempt, setback and decision a reason to matter.
