​It's hard to imagine anyone who is not watching Game of Thronesand nearly impossible to think that someone who is about to star in the highly-anticipated spinoff hasn't seen any of the series. But that's apparently the case with ​Naomi Watts who, after being cast in the Thrones prequel series, had to get to work on watching the show.

While speaking to Entertainment Tonight, Watts admitted she's just now getting into the hit HBO series, but is already "beyond" a fan.

"I am late coming to it, I have to say," Watts said. "But that's how I am with lots of things in life. I am bingeing it right now and studying. It's very exciting."

Watts's character's name in the prequel is not known at this time, but according to Variety, she will play "a charismatic socialite hiding a dark secret."

The prequel series is set thousands of years before the events of Game of Thrones, in the Age of Heroes. Fans have been speculating since it was only ​rumored that Watts was being cast that perhaps she could play an ancestor to the House Lannister, as her physical features match the family in the TV series.
