Did you guys already read about Iain Glen's interview in Taormina film festival, kindly translated by a dear fellow fan who knows Italian:
Voglio solo seguire gli altri! — An interview with Iain Glen in Taormina by Eva...
It is really promising, I think... I've got an amazing feeling about it.
Especially this part:
“As an actor, you are always looking for some good news about your role and about your character’s development. I believe something good, really good is coming. I was able to speak with HBO […] and…well, it seems like we will soon have a lot of interesting changes and developments, not only for my character, of course”.
