Here's how I do a TV series pitch document (format):
TITLE
THE SERIES (what the show is, tone, why it's cool/relevant)
LEADS (character descrips w actor reading it in mind)
CREATOR'S NOTE (why I can write it)
PILOT SUMMARY
PILOT OUTLINE
SUMMARIES OF NEXT EPS (stories, arcs)

Sometimes to sell a pilot, I've just done a pre-format pitch -- basically everything but the last 3 things. Then added those 3 items for the format. This was short, like 2-5 pp, other times, longer. The format, more like 20pp or more.

PS: For future episodes, I find it useful for execs if you summarize the summary first. Like a good description you might see when you select a streaming episode (the basic storylines) then go into the details. For the series, it helps to bring up structure.

This is what works for me, in case it's useful. xx

Oh, and obviously this looks very rote and simple in this sketch, but make no mistake like, I do this, but, in execution, try to write my ass off in each section & wow their socks off.

My bad. I think many people misunderstood what I meant by this which is about a written document called a format or bible which is a written pitch often required by networks. This isn’t about verbal pitching.

But I have sold pilots w a spec format document after a verbal prepitch of the premise and series highlights. So it’s a useful skill to write them bc you will prob need to before or after you sell a series.
