I've done the math and in my opinion, the more material you write, the greater chance you have of success. I've written 36 screenplays and teleplays and some are better than others. Nevertheless, I've pitched most of my work at one time or another.
Several years ago, a producer I know was looking for a historically based story for the History Channel. My wife suggested writing something about African American baseball during the early 1930's. I did some research and created a baseball/gangster called story called The Other League based on real Pittsburgh Crawfords team owner, Gus Greenlee. Though History Channel passed on our pitch, the VP at Tyler Perry Studios read and loved the script. He elevated it to the studio President, who read and ultimately turned down the project. Though there was no sale, having TPS read the screenplay was pretty dang cool, especially with both the top execs involved. Since then, I've done very little with this screenplay because it's a pricey period piece.
Last week, I pitched my Angela Davis script to a producer looking for historical stories for female African American leads but also mentioned the The Other League at the end of my email. Yesterday, the producer sent me a note saying Send me the epic gangster script about African American baseball.
You may write something and not do anything with it for several years. However, opportunities can present themselves at the most unexpected times. So in my opinion, writing more material creates more opportunities.
