What I find fascinating from TheDailySuperHero's info on the Dr. Strange movie is this direct quote from the source who's leaking this:
"What I can say is that Strange is being groomed to be the next Iron Man. The studio needs a new 'hub' character going into Phase 3 and beyond, as there is audience fatigue, aging stars and a need to move from Tony Stark/Iron Man as a 'hub' for films."
So if there's any truth to this at all, Strange isn't some one-off movie; it's supposed to be more or less the centerpiece of Phase III. Some of us, myself included, speculated many years ago that the "phases" would be divided into "themes," and even Feige alluded to it: Phase I = superheroes rise/ Avengers Assemble; Phase II = cosmic expansion; Phase III = magic and supernatural. Could we expect other Phase III films to deal with magic of some sort, then?
