I was fortunate enough to attend a TV writing workshop by Chad Gervich. Here are the elements of a perfect pitch:
EMOTIONAL INTRODUCTION – to engage your audience and sell the passion
LOGLINE – 1 sentence outlining the premise
SYNOPSIS – 1 paragraph
SUMMARY – 1 page overview
CHARACTER DESCRIPTION – how the main characters view the world
EPISODE/PLOT OUTLINE – a sample episode should be a typical episode rather than a pilot which sets up the series. Write 1-2 of these.
SAMPLE OUTLINE – outline 6-8 episodes in 1-2 lines each to demonstrate the show has longevity.
FUTURE SEASONS – Even stand alone shows have a degree of serialization, usually in the B and C stories.
UNIQUENESS – Show your individuality. Why can you be the only person to write the show? How is it familiar, yet different?
