The 2016 sequel to "Days of Future Past" will focus on the cast of "X-Men: First Class," according to the co-writer and producer.

X-Men: Days of Future Past may bring Patrick Stewart, Ellen Page and the rest of the cast of the first three X-Men movies back, but don't expect them to make it to the follow-up, X-Men: Apocalypse.

Talking to Empire magazine, Days of Future Past director and X-Men franchise producer Bryan Singer called the 2016 project "more of a First Class sequel" and added that the cast of the first trilogy will not appear in the movie.

STORY: Release Date Announced for 'X-Men: Apocalypse'

He also dismissed rumors that Apocalypse would spin out of a Days of Future Past postcredit sequence where Michael Fassbender's Magneto becomes possessed by an alien known as Apocalypse. "That's not the case," Singer said. "People were concerned we were making Apocalypse an alien. It's odd. I don't know where that came from."

Instead, the movie version of Apocalypse looks set to follow the lead of the comic book version and be a character from ancient Egypt. "What would people thousands of years ago, without the benefit of science, think mutants were? And more importantly, what would mutants thousands of years ago think they were? Gods? Titans? Angels? Demons?" Singer asked. "If such mutants did exist thousands of years ago, what became of them? Did one survive?"

X-Men: Days of Future Past will be released in May of this year, with X-Men: Apocalypse due in 2016.
