An instant classic in the field, STSA is essential reading for any screenwriter, and helpful for novelists, too. Gulino joins Aristotle/Syd Field (3-Act) and Joseph Campbell/Chris Vogler (Mythic) by offering a third paradigm of screenplay structure, the Sequence Approach.
90% of the value of the book lies within its first 19 pages, where Gulino lays out the sequence approach and discusses its merits, in addition to a fine--no, an outstanding--primer on the basic principles of drama. The rest of the book merely illustrates the sequence approach in a variety of films, which is helpful--don't get me wrong--it's also just a great deal of plot summary to plow through. The book runs on for 222 pages because it needed to be long enough to be called a book, but if you're looking for the action, it's in the first 19 pages.
Screenplays are commonly conceived in acts, scenes, and beats, with a few sequences that extend several scenes. Gulino asserts that a sequence, like a paragraph, is an essential unit of composition in film, and that most narrative films can be composed and analyzed by breaking them down into a string of sequences from start to finish. The author offers a standard 8-sequence template for sequencing a screenplay: two in the first act, four in the second act, two in the third act, but what I love about this book is that, unlike many other formulaic screenwriting approaches, the sequence approach is flexible enough to be stretched or compressed as needed to accommodate a wide variety of films. We see in the book how sequencing can work for films as conventional as Air Force One and Toy Story to more unconventional films like Nights of Cabiria and Being John Malkovich.
Gulino shows how the sequence approach simplifies composition and assists the writer in identifying and tracking dramatic tension throughout the script. The sequence approach also helps to better integrate subplots and sheds light on non-traditional narrative approaches that cannot be accounted for in other structural paradigms.
Once you've been introduced to sequences, you'll never go back. They're an immensely helpful tool for composing and analyzing narratives of all kinds.
Yo ho, yo ho, the sequence approach for me.
