It's simple: films need to have commercial value for the studios to produce them, distributors to sell them, and theater chains to screen them. While talent definitely plays a part in the writing process, it can be the well-executed formulaic approaches to the popular genres that will first get you noticed in the industry.

Genre Screenwriting: How to Write Popular Screenplays That Sell does not attempt to probe in the deepest psyche of screenwriters and directors of famous or seminal films, nor does it attempt to analyze the deep theoretic machinations of films. Duncan's simple goal is to give the reader, the screenwriter, a practical guide to writing each popular film genre. Employing methods as diverse as using fairy tales to illustrate the 'how to' process for each popular genre, and discussing these popular genres in modern television and its relation to its big screen counterpart, Duncan provides a one-stop shop for novices and professionals alike.
