Lee Jessup is a script consultant that advertises a lot! This morning I found this post Called Experts Weigh In In: The First Ten.
Nope, they're not referring to the first ten yards of a drive in a football game. Lee's article is addressing the first ten pages of a screenplay. I believe in opening big and often deliver the inciting incident in the first 5 to 10 pages. This is the way I've always written. Yet, I often read scripts where the first ten are a snooze fest. This can also be a good indicator that the whole script may be a cure for insomnia. I subscribe to the philosophy of lean writing. To me, this means if it doesn't add value, get rid of it. It's kind of like hang gliding. You want the wind of the story to sweep you along. Not weigh you down like an anvil.
