The extreme version of this structure is Save The Cat[1] where each of the beats should happen on this page number of your script. Like others have mentioned these are largely based on the Hero with a Thousand Faces by Joseph Campbell.
Save the Cat specifies page numbers because scripts are formatted to one page/minute of screen time, and movies have ideal lengths.
If you can't turn to the exact center page and find the climax, the script is either formatted wrong (wasting your time) or written wrong (wasting your money).
Overall, when someone says _my favorite movie X_ doesn't fit this pattern or _legendary novel_ Y doesn't do this at all -- well, sometimes they might be right about that, but many, many non-linear movies and books still hit the beats Save the Cat describes.
