Show(s) Worked On: Once Upon A Time, Battlestar Galactica, Caprica, Buffy the Vampire Slayer, Husbands

Jane Espenson has done it all: worked on huge network shows like Once Upon A Time; shepherded a wonderful web series through production with Husbands; and can claim credits on not one, but two, of the greatest cult hits of all time, Buffy and Battlestar. Luckily for us, she's always dispensing advice for creative minds on Twitter.

Rather than write jokes, Espenson plays the part of the phenomenal screenwriting teacher you never had. She conducts "writing sprints," encouraging followers to write along with her, live tweets her shows, and links to article about the industry. For most of us, the doors to Hollywood are locked from the inside, but following Jane Espenson will at least give you a small peek in the window.
