It seems like every single site reporting that Bryan Singer will be returning to direct the next installment of the X-Men franchise is leaving out something significant.

This quote from writer Simon Kinberg from an interview with Yahoo:

If we included some of the original X-Men, like Storm and Jean and Scott and others, in Apocalypse, yeah, we would have to recast them, because Apocalypse takes place a good 20 years before X1, which now, insanely, was 10 or 15 years ago. It’d be very hard to do. Halle [Berry], and Famke [Janssen], and Jimmy [Marsden], and others have done such wonderful jobs of bringing those characters to life, and they’re so identified, those actors, with the parts now. So, it would be a tall task, but I also would have said, before First Class, that there would be no way we could find actors who could stand alongside Ian McKellen and Patrick Stewart, and I think we managed to with Michael [Fassbender] and James [McAvoy] doing their own interpretations of the characters, not doing an impersonation. So, are we going to have to recast? If some of those characters were in the movie we would, but we will see.

If anything, this could possibly mean more for the franchise than director (and fully exonerated) Singer.
