Josh Whitehouse has officially joined the cast of HBO’s Game of Thrones prequel.

Whitehouse, best known for his role as Hugh Armitage on Poldark and as Nicolas Cage in the remake of Valley Girl, is expected to star opposite of Naomi Watts, who also recently joined the cast series. Whitehouse and Watts’ character details have been kept under wraps, but a few hints about Watt’s character has been revealed. Her character is expected to be along the lines of “playing a charismatic socialite hiding a dark secret.”

Recently, Game of Thrones author, George R.R. Martin wrote on his blog that the show’s title will be The Long Night, however, HBO has yet to confirm to this. 

The prequel which will be written by Martin and Jane Goldman, writer of Kingsman: The Secret Service and X-Men: First Class is expected to begin production early next year. The prequel will take viewers back thousands of years before the events of Games of Thrones and it will explore “the world’s descent from the Golden Age of Heroes into its darkest hour,” the network said. “And only one thing is for sure: From the horrifying secrets of Westeros’ history to the true origin of the white walkers, the mysteries of the East, to the Starks of legend… it’s not the story we think we know,” it continued. 


Goldman and Martin’s Game of Thrones prequel is only the first of many potential series that are set in the world of Westeros to be produced at HBO. Last year in May, many writers revealed that they were working on what Martin describes as “successor shows.” These writers include Goldman, Kong: Skull Island’s Max Borenstein, Legends Brian Helgeland, Westworld’s Carly Wray and Game of Thrones veteran Bryan Cogman. Game of Thrones creators and showrunners, David Benioff and Dan Weiss are said to not be involved with any of the successor show efforts. 

While speaking with The Hollywood Reporter, HBO programming president Casey Bloys said that if and when any Game of Thrones successors are approved, they will not air “until at least a year after the final season” of Games of Thrones. Bloys also revealed that not all successor scripts will move past the page. 

The final season of Game of Thrones will air sometime within the first half of 2019.
