9. The Blackfish

Brynden Tully a.k.a. The Blackfish is a prime candidate for the 'Game of Thrones "I have absolutely no idea what your name is" Award' among casual fans, but he's back for Season 6, raising some very interesting questions about the Riverlands. It wasn't even known whether the character survived the bloody aftermath of the Red Wedding until now, but Clive Russell has been spotted on a Northern Ireland set in battle gear ready to square off against a familiar face and major foe.
