GoT prequel 'House of The Dragon' casts three more stars

The series consisting of 10 episodes will air on HBO and stream on HBO Max, although there has been no news on the release date.

The series, which is dated 300 years before the timeline of Game of Thrones, cast its first actor, Paddy Considine, for the role of King Viserys Targaryen, who now has a far nobler character from GoT's portrayal.

The latest round of casting starts with Cooke, who incidentally is the only actor portraying a role outside the Targaryen dynasty as of now.

Cooke plays Alicent Hightower, a woman of immense wit and magnanimity in the series.

The HBO synopsis states Alicent as the daughter of Otto Hightower, the Hand of the King.

Alicent is privy to the king's innermost circle.

Then comes D'Arcy, who plays the role of Princess Rhaenyra Targaryen, who seems to keep fighting an ensuing battle with her entitled position and her personal struggle.

The HBO synopsis describes the character as "The king's first-born child. She is of pure Valyrian blood, and she is a dragonrider. Many would say that Rhaenyra was born with everything...but she was not born a man."

Finally, it's time to describe the baddy in the lot, and Matt Smith is doing the honors by playing Prince Daemon Targaryen.

The show describes Daemon's character as unpredictable in a beautiful manner.

He is the younger brother of King Viserys with true blood of the dragon, but the description reads, "Whenever a Targaryen is born, the gods toss a coin in the air."
