A Knight of the Seven Kingdoms: The Hedge Knight has begun to announce their cast of characters, but I am still waiting for one character to be recast in this next Game of Thrones show. Production has announced several characters, including the show’s two lead stars, Peter Claffey as Ser Duncan The Tall (Dunk) and Dexter Sol Ansell as Aegon Targaryen (Egg). Other notable characters that the show has announced include Finn Bennett as Aerion Targaryen (Aeron Brightflame), Bertie Carvel as Baelor Targaryen (Baelor Breakspear), Tanzyn Crawford as Tanselle, Daniel Ings as Lyonel Baratheon, and Sam Spruell as Maekar Targaryen.
