The first look at HBO's Game of Thrones prequel series has leaked online.

In the photo that's surfaced on Twitter, Naomi Watts can be seen in costume on the show's top secret set in the Italian town of Gaeta.

The photograph was taken last month ahead of the shoot's completion in Northern Ireland.

Watts plays “a charismatic socialite hiding a dark secret” and her appointment brings a particular gravitas to something many may have written off as a cash in.

Fans have speculated she could be playing Nissa Nissa, the wife of ancient hero Azor Ahai. He’s the Lord of Light who, according to legend, created a magical sword called “Lightbringer” which was used to defeat the White Walkers.

You can see the photo below.

While a title is yet to be unconfirmed by HBO, reports suggest the prequel will be titled Bloodmoon.

Not much is known about the storyline, but author George RR Martin recently revealed some tantalising details of what to expect when the show arrives.

Watts' co-stars include Naomi Ackie, Josh Whitehouse and Harry Potter star Miranda Richardson. You can find a compilation of everything we know about the series here.
