When a franchise goes big, you have two choices for what to do next. You can zoom out and reveal the wider context of the original story, or you can zoom in and spotlight a story that has lower stakes. This latter approach is high-risk, high-reward, but it could serve to completely redefine the entire property. Take, for example, the DC Universe.
In classic Thrones fashion, the trailer presents a medieval world of knights, kings, squires, peasants, dragons and, if Egg is to be believed, at least one magical comet. The series also stars Finn Bennett as Prince Aerion Targaryen, Bertie Carvel as Prince Baelor Targaryen, Sam Spruell as Prince Maekar Targaryen, Daniel Ings as Ser Lyonel Baratheon and Tanzyn Crawford as Tanselle, a Dornish puppeteer.
