While much speculation for the next X-Men movie has centered around what older characters would re-appear, it seems like one of the writers is listening and knows of a few fan favorites that should be showing up in younger versions.

Speaking with Yahoo! on Monday, writer/producer Simon Kinberg talked about what fans could expect from X-Men: Apocalypse and what the story will focus on.

"The X-Men film that we're working on now as everybody knows is X-Men: Apocalypse and that really follows the stories of the let's say 'First Class' X-Men. Jennifer Lawrence, Michael Fassbender, James McAvoy, Nicholas Hoult, many others of that generation of X-Men," Kinberg said.

"So, in future X-Men films? Perhaps, but in Apocalypse it will really be the continuation of the 'past' of Days of Future Past."

He added that a few familiar faces could be re-appearing, much like in Days of Future Past, but this time they may be re-cast with younger actors as the roles will be expanded.

"If we included some of the original X-Men, like Storm, Jean, Scott, and others, yeah we would have to recast them, because Apocalypse takes place a good twenty years before X1, which now insanely was fifteen years ago," Kinberg said.

"It would be very hard to do. Halle, Famke, and Jimmy, and others have done such wonderful jobs of bringing those characters to life and they're so identified, those actors, with the parts now."

Kinberg said that while people may not like seeing new faces in the familiar roles, it has worked before with Michael Fassbender and James McAvoy in First Class.

"So it would be a tall task, but I also would have said before First Class there would be no way we could find actors who could stand alongside Ian McKellen and Patrick Stewart," Kinberg said.

"And I think we managed to with Michael and James finding their own interpretation 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'll see."

X-Men: Apocalypse is set to open in theaters on May 27, 2016.
