It’s especially interesting to me that the Russo’s added the Infinity Stone bit.
This is definitely good news for Marvel who have been wanting to see more of Red Skull over the years.
Does this mean that Red Skull is going to make a move in Avengers 4?
If anything, the Russo’s might just be leaving the door open for someone to do something with Red Skull in the future, but for a character who people thought they’d never see again, this is exciting stuff.
