Wright says he will be returning to Game of Thrones season 6 as Bran Stark.

I can’t say a lot, but I am back this season, and it’s going to get particularly interesting with Bran. He has some interesting visions.

He also talks about whether Jon Snow will come back;

I wish he would because I love Kit and because the character’s so cool. Who knows? We start filming series six at the end of this month [July] so we’ll see.
