Entertainment Weekly brings us the news:
The biggest new Game of Thrones role is going to…
Ciarán Hinds! (ed. pronounced KEE-rawn)
The Rome actor has been cast as Wildling leader Mance Rayder, the King Beyond the Wall. Rayder has united the disparate clans of the Far North behind a single mission: To attack The Wall. He’s been frequently referenced (though unseen) in the HBO hit fantasy drama’s first two seasons. In the second season finale, undercover Night’s Watchman Jon Snow (Kit Harington) was being taken to meet Rayder.
The third season on HBO starts 31 March 2013.
