I'm trying to work on this concept I have for a limited-run series, in an hour-long format. Right now, since I figure the idea would probably work better for pay cable channels like HBO or Showtime, I'm wondering what the act structure is for hour long dramas on those channels (i.e. DEXTER, TRUE BLOOD, TREME, THE TUDORS, etc.) Also, how many story beats are in an hour long drama? Just wondering.
