Hollywood is an odd place and ever-changing. If your literary agent or publisher wants to pitch your book to producers, managers or networks, they need to know the rules—or at least, the rules of the day.
But don’t get too stuck on them, because … you guessed it … they’ll change. Often.
Back in the day, an agent or publisher could pitch your book over the phone or mail a copy off for consideration. Now, the execs prefer a little more detail and insight before considering your story for an adaptation.
The million-dollar question: What does Hollywood want in a story?
Truth is, sometimes they don’t even know until they hear it. It’s a gut check of something that’s not only marketable, but also gives them tingles when they read the logline.
