Another McCallum interview, as per our front page, has him quoted as saying the live-action show is like, "Deadwood in space".
I find this bold... they've hinted in the past that Lucas was kind of enamored with the HBO series like Rome or Deadwood, and I can only imagine he's into Game of Thrones, but hinting that the new show could be anything like Deadwood is pretty specific.
I have a hard time believing this... There's a difference between what Deadwood was, and simply not gearing something towards kids at all. There's a hefty grey area between those two things I think, so I find the comment hard to live up to.
