The film's screenwriter and producer Simon Kinberg said "the next movie takes place in 1983" or 10 years after "X-Men: Days of Future Past", reported Ace showbiz.
Kinberg has already confirmed that the upcoming film would be more of 'First Class' sequel and would involve some of the original cast.
'Apocalypse' would "present a new leader (other than Magneto and Professor X), the darkest leader in the movie franchise," he said.
Set for a May 27, 2016 release in the US, the film will bring back Hugh Jackman as Wolverine and Evan Peters as Quicksilver.
