With Chris Chibnall coming in as showrunner, it's no surprise he's turning to his previous hit series, Broadchurch, to fill some of the roles on the show. And aside from star Jodie Whittaker, we get another Broadchurch actor in this trailer, with the appearance of Shaun Dooley.
He's not one of the new friends, but since he crops up a couple of times we can assume he has a sizeable guest role in at least one episode.
