If you’ve gone to the movies recently, you may have felt a strangely familiar feeling: You’ve seen this movie before. Not this exact movie, but some of these exact story beats: the hero dressed down by his mentor in the first 15 minutes (Star Trek Into Darkness, Battleship); the villain who gets caught on purpose (The Dark Knight, The Avengers, Skyfall, Star Trek Into Darkness); the moment of hopelessness and disarray a half-hour before the movie ends (Olympus Has Fallen, Oblivion, 21 Jump Street, Fast & Furious 6).
It’s not déjà vu. Summer movies are often described as formulaic. But what few people know is that there is actually a formula—one that lays out, on a page-by-page basis, exactly what should happen when in a screenplay. It’s as if a mad scientist has discovered a secret process for making a perfect, or at least perfectly conventional, summer blockbuster.
The formula didn’t come from a mad scientist. Instead it came from a screenplay guidebook, Save the Cat! The Last Book on Screenwriting You’ll Ever Need. In the book, author Blake Snyder, a successful spec screenwriter who became an influential screenplay guru, preaches a variant on the basic three-act structure that has dominated blockbuster filmmaking since the late 1970s.
