Arc

The internal development of a character over the course of a film – that is the arc. Not the plot itself, but how the person changes, what they learn, which internal resistances they overcome, or even how they fail. On set, you immediately notice whether an actor has understood this arc: they don't play with the same energy in scene one as they do in the climax. The voice changes, the gaze becomes different, the physical presence matures or disintegrates – depending on where the journey leads.

On set, this means concretely: you as the director must not only tell the actors what to do, but where they stand emotionally. A character who is cowardly at the beginning and shows courage at the end needs stages in between. Scenes that give space to this transformation. Sometimes these are big, visible moments – an argument, a victory, a betrayal. But often they are small, internal shifts: holding a pause longer, speaking a line softer, letting the hand tremble. The camera angle follows this logic – moving closer when the character becomes more vulnerable, further away when they gain power.

The arc is not the same as the plot line. You can have a wild, eventful story and still have no real character arc if the person is the same at the end as they were at the beginning. Conversely, the external action can be minimal – a conversation in a car, a night in a room – and the arc can be immense because the inner world shifts fundamentally. The best screenplays weave arc and plot together, so that every action is also development.

Practically: when you read a script, mark the moments where the character abandons or adopts a belief. These are the anchor points of the arc. In the edit, you then see if you have enough material for these transitions. An arc needs credibility – don't jump from here to there without bridging scenes. And: a flat arc is sometimes the right choice. Not everyone has to change. Some characters are tragic because they don't.
