Speaking exclusively to CultBox earlier today, Fisher-Becker revealed: “I’m doing a couple of episodes of Game of Thrones soon, it’s all very exciting. I’m a High Priest. Exciting times!”
Of course, the priests in the world of Westeros are called septons. So it looks like Fisher-Becker will be filling the role of the High Septon. The High Septon is basically the pope of the faith of the Seven. Fisher-Becker is perhaps best-known for his recent guest role as Dorium Maldovar on Doctor Who. You may also recognize him as the Hufflepuff house ghost Fat Friar from Harry Potter and the Sorcerer’s Stone.
Winter Is Coming: Not much to add here. Looks about how I imagined him. Will wait for official confirmation from HBO before adding him to our cast gallery, but it looks legit.
