I read in writing a screenplay, you definitely need an inciting incident. The inciting incident is an event in a story that upsets the status quo and begins the story’s movement, either in a positive way or negative, that culminates in the climax and denouement.
Now, we know why. What about the where and when do you place the incident in the story. I know it's in the first act, but where, what amount of time do you take to set it up? Is it within the first ten, fifteen, or whenever you make it happen? Would sixteen minutes in a feature be correct or stretching it a bit? What about a mini one on the second page and the big one on the sixteenth page.
It seems most of all the movies I've watched, it has been within the first ten minutes. Then we all know where the protagonist is heading. What do you think?
