It has been revealed today that Freddie Stroma, who played Cormac McLaggen in the Harry Potter films, has been cast in Game of Thrones for the show’s 6th season. He will be playing Dickon Tarly who is the brother of Jon Snow’s best friend Samwell Tarley.

Dickon has not been seen in the books but readers do know that he is the second oldest son of Randyll Tarley and is heir to his family’s title since Sam gave it up to join the Night’s Watch.
