Like I've said before in another thread, I think in many ways RTD/Julie Gardner have used the TW brand as a way of becoming household names in America. They see it as a stepping stone perhaps, so I wasn't too surprised by Rusty's comments on BBC Wales News this week if I'm honest.
There aren't many writers/showrunner wannabes that I can see going over to America to take over TW unless it becomes incredibly successful, and on Starz I can't see it getting more than a million or two viewers at most. Which means that it will probably go to someone like Jane Espenson (who has written most of Miracle Day) rather than another Brit writer. Not being a Chibnall fan a big part of me sighs with relief if I'm honest
