Deadman and Hela
I don't know if it has been officially announced that Cate Blanchet will be playing Hela in Thor: Ragnarok, but that seems to be the general consensus of what her role will be. I hope so, because I have always enjoyed the character in the comics, and Blanchet is perfect for the part.  Hopefully we will see some of that great Hela headgear as designed by Jack Kirby or Walt Simonson.
