In Screenplay: The Foundations of Screenwriting (1979), Syd Field first popularized the Three-Act Paradigm of Setup, Confrontation and Resolution for conceptualizing and creating the Hollywood screenplay. For Field, the budding screenwriter needs a clear screenplay structure, one which includes two well-crafted plot points, the first at the end of Act I, the second at the end of Act II. By focusing on the importance of the four essentials of beginning and end, and the two pivotal plot points, Field did the Hollywood film industry an enormous service. Nonetheless, although he handles the issue of overall structure expertly, Field falls down when offering the screenwriter advice on how to successfully build each of the three individual Acts. This is because Field did not recognize the importance of another layer of analysis that underpins the existence of plot points. This is the level of the plot genotype.
