Longshot Pictures
I was called down to Paramount off my very first spec script. At the time, Star Trek allowed 50 people a year to come to the William S. Hart building and pitch ideas. To earn that pitch, I beat thousands of other writers with my spec submission. I've been writing ever since. I give seminars at Universities and in Los Angeles for organizations like Colab. I've won pitching contests and excel at synopsis and loglines. I've also produced films streamed and distributed by Netflix, Eone, Lionsgate, and MGM. I'm a writer at heart, though. Experienced writers know that writing is not a science, it's an art. Structure is a guide. Structure will not elicit emotion from the audience. Your story needs to. Showrunners and Directors believe they can be writers because they've studied how to follow some "structure recipe." Structure is a science. Story is an art. Know the difference.
