Some of you are probably thinking about contributing to our script this week but don’t know how to get started. One question I’ve been hearing is, “How much should I write?”

The short answer: It depends on what kind of scene you have in mind.

The rules say 1-5 pages, which is a pretty big spread. There are going to be times when one elegant page at a key juncture will turn the story just so, exciting readers with a new take on what’s happened, challenging or enlightening them and inspiring them to pitch in themselves.

Other times, it may take 4-5 pages to string together a compelling action sequence complete with unexpected developments and distinctive dialog.

My own contribution, the first three pages, fell somewhere in the middle. You’ll notice that I could have stopped after the one-and-a-half-page opening sequence that takes place mostly in the tunnel. But this being the setup, I wanted to reveal that the rumpled and possibly shady Napolitano character is in fact L.A.’s mayor. And I wanted to put him in an upscale setting and introduce Celeste, who I think may turn into a main character.

The next pages should… Wait a minute—that’s your job.

Deadline’s Sunday.
