Brief character bios – Focus on your core cast here, and one or two minor characters if they’re particularly relevant. You guessed it, keep this brief too. Talk character types instead of casting the roles with actors you envisage playing the roles. Mention strengths, weaknesses, character goals and emotional needs, as well as telling us about the personal development of each character (unless this is a sitcom, where characters generally stay the same throughout a series)
Extras – There are tons of other components that you can throw in if you choose to. Just remember, on each page, your focus needs to be on hooking the reader. Make sure your show guide reflects the tone of your series. If it’s a comedy, make sure your bible is funny and entertaining etc. Concept art, pages of script, location details, style, and what’s original about your idea are all extras that can help sell your idea.
Camera angles - Do not just write dialogue, but also describe what is going on in the scene. What is the general atmosphere of the scene? How do the actors move? You should also include camera angles.
