If any of you guys want to read the show's script, not all the episodes are open to the public, but the pilot is.

It's really interesting to see what Stephen included in the script but didn't make it into the episode, such as a close-up of an old picture of the Shelby brothers in their home. If you re-watch the episode while reading the script you can also take note of small dialogue changes the actors made, though there aren't many. Also, the scene order in the official first episode is a bit different than the order in the script, which is interesting as well.
Edit:
I just realized that the Series 2 Episode 1 Script is also open to the public.
