Game of Thrones Season 7 may prove even less opaque than the ultra-secrecy of Season 6, but its British actor bingo remains on point. Harry Potter star Jim Broadbent has joined Season 7 in a major role, so put on your speculating tin foil!

Entertainment Weekly broke word of Broadbent’s casting, but of course, exact details of the character remain under wraps. The role is said to be “significant,” but may not be among the recent round of casting reports.

In the meantime, HBO has confirmed that Game of Thrones Season 7 will start production on a shortened seven episodes this coming year, with an aim to premiere in Summer 2017. A list of directors for the year has also been announced, along with some major set pieces, while at least a portion of filming will take place in Iceland.

Broadbent is also well known for major films like Hot Fuzz or Indiana Jones and the Kingdom of the Crystal Skull, but who might his Game of Thrones Season 7 character represent?
