Word out of Disney's D23 Expo is that "Game of Thrones" star Kit Harington is joining the MCU.

But, like Jon Snow himself, we have to admit we know nothing at this point.

Still, the collision of these two titanic fandoms is news indeed.

Fellow "Game of Thrones" star Richard Madden was previously announced to star as Ikaris in "The Eternals," opposite Angelina Jolie

At one point, Mother of Dragons herself Emilia Clarke was in consideration to play the lead villain in "Iron Man 3," but, apparently, Marvel CEO Ike Perlmutter thought fans wouldn't buy an action figure of a female villain and the script was rewritten.

We'll add more details as we learn them about Harington's MCU role.
