Unlock the Hidden Trick Every Screenwriter Swears By to Transform Their Third Act Overnight
Would Aliens have still worked had there never been a setup scene for that construction loader suit? Sure. But when you create the setup scene, it operates as this line connecting the earlier part of the screenplay to this part of the screenplay, and, therefore, it makes the story feel unified. Or, to put it more bluntly, it doesn’t feel like the writer was just making up the ending as he went along.
I brought up Back to the Future earlier because I don’t think it’s a coincidence that the best third act in history also has the most third act payoffs in history. If there’s ever an argument to be made about how important payoffs are to making a third act great, look no further. It’s one payoff after another here.
