Naomi Watts will star in 'Game of Thrones' prequel pilot on HBO that hails from Jane Goldman. Watts will apparently be playing the lead role in the pilot episode which will be written and produced by Goldman along with George RR Martin.

According to Deadline, though the GOT team has not given away too much of information about Watt's character, it was revealed that she will be playing a charismatic socialite who happens to be hiding a dark secret.

Martin also took to his website and released a statement saying that he is happy to have Watts onboard. "I could not be more excited. Welcome to Westeros, Naomi." He also hints that there will be more information revealed soon. 

Recently Casey Bloys, HBO's president of programming, told Deadline in an interview that the show will feature different characters. So there is no reason to be worried that the actress will steal all the spotlight in the first episode. “There are very strong female characters but it’s an ensemble, there are men and women,” Bloys revealed. “Jane is a very good writer, we don’t want to limit her to writing female leads. There are a lot of very complicated leads in (the pilot).”

The new prequel which is one among the five projects that might evolve from the original show will take place 1000 years before the events in the current series 'Games of Thrones'. 

“The series chronicles the world’s descent from the Golden Age of Heroes into its darkest hour,” HBO revealed in a statement to The New York Times earlier this year. “And only one thing is for sure: From the horrifying secrets of Westeros’s 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.”

Season 8, which is the final season of 'Game of Thrones' is all set to debut in 2019.
