Stephanie Blacker tweeted this an hour ago:

And her agency has added the Game of Thrones mention back to their News. (It was deleted after WiC posted that they’d discovered her casting that way.)

Still no confirmation of who she is playing, but she’s filming in Belfast, so hopefully more info will leak. Thomas Brodie Sangster was also spotted in Belfast today. I think they’re still filming multiple storylines at once, and they’ve got stuff going on in Dubrovnik at the same time. Wild filming schedule this year.

“Three great men- a king, a priest, and a rich man. Between them stands a common sellsword. Each great man bids the sellsword kill the other two. Who lives? Who dies?
Power resides where men believe it resides. It’s a trick, a shadow on the wall, and a very small man can cast a very large shadow.”I love Varys’s prominence in the new trailer. Conleth Hill has done a fantastic job.

One of my WiC blurbs. My less-appropriate reaction is FUCKING CONLETH HILL IS THE FUCKING MAN. GOD BLESS NORTHERN IRELAND FOR PRODUCING SUCH STELLAR ACTORS AND FUCKING BEAUTIFUL SCENERY.
Okay, got it out of my system.
