Game of Thrones’ Prequel Casts Naomi Watts in Lead Role

She is such a good actress. No matter what her role is, she'll be FIEEEEERCE!
So psyched for this prequel.

Anyone have any theories of who she could be? Nissan Nissan? A Valerian? or a Lannister? I've even heard maybe 'Lan the Clever'...

That would be a cool twist.

I tapped out of THRONES two seasons ago, so you'd have to have something pretty great up your sleeve to pique my interest in any sequel, prequel or spin-off.
