Hmmm. So the actors in the Marvel movies are slowly beginning to back out of future movies. Strangely, at the same time, Marvel is making changes to the gender and race of characters... which will probably require recasting them. I wonder...
The changes are happening in the comics which other than title have really nothing to do with the movies. Comic Thor is going to be a woman for a while, probably not even long enough for them to make another Thor movie, and it will have no impact on the movies.
