In screenwriting, the Tightrope represents the protagonist's path toward the desired goal becoming much more treacherous and risky. The complications are more severe and the protagonist has much more to lose if the journey is a failure.
toc_collapse=0;The Tightrope is used to create high anxiety within the story. It is in this segment of the script where the protagonist is going to progressively fail much to the delight of the antagonist.
The Tightrope segment of the script runs from the midpoint of the script for the next 25% of the script (if the script is 120 pages, the Tightrope runs from page 60 to around page 100) This means creating an exciting but angst-ridden path for the Protagonist.
If done correctly, the Tightrope will end with the Apparent Defeat of the protagonist, creating a deep sense of hopelessness in ever reaching the desired goal.
