Tom Wlaschiha is the latest addition to the expanding Game of Thrones cast: the German actor has been cast as assassin Jaqen H’ghar!

Game of Thrones fansite Winter is Coming first reported this news. Jaqen is one of the criminals being taken to the Wall along with Arya Stark, and is described by HBO as:

Sly, enigmatic, and a dangerous criminal, part of Yoren’s group of recruits taken from King’s Landing to join the Night’s Watch. A foreigner from the Free Cities, he speaks broken English. Seductive, charming, and very dangerous.

Further, the book describes him as having dual-coloured hair, one half white and one half red. Do you think they’ll do this in the TV series, too?
