Second season casting is in full swing, yes.
And we're close on a few roles. Choices made, that is to say, but now we wait on HBO approval, and then of course we have to make a deal. Not all deals close, much as you would like them to. There's budget to consider, scheduling, all sorts of things.
On other roles, well, we've seen a lot of readings, but we're not in love yet. So the auditions continue. In Ireland, in London, even in LA.
Bottom line: no one has been cast yet, so stop holding your breath.
When we do sign some new cast, Froggy will give you the hints.
(Unless someone else breaks the news first).
((Or unless it's after June 13. That's the day I leave for Poland. I'll be out of the loop while overseas, so after that date, the announcements are more like to come from elsewhere)).
