Hugh Jackman may appear in X-Men: Apocalypse before Wolverine 3, and the two films could shoot back to back.
At the recent X-Men: Days of Future Past press day in Los Angeles, the topic naturally turned to the next two installments in the X-Men franchise, X-Men: Apocalypse and Wolverine 3. Producers Lauren Shuler-Donner and Hutch Parker were fairly candid about their plans, which sound like they will involve shooting the films back to back.
Regarding the scheduling, Lauren Shuler-Donner said that "we announced Apocalypseto come out in 2016, so that means we have to shoot next summer. And then we’d have to shoot our new Wolverine movie either before or after that. I think after because it will come out after."
Mr. Parker added that "the goal will be Apocalypsefor 2016, which means at the latest [filming begins] in summer 2015, and then the same thing with Wolverine, either before or after, but based on the script." So, assuming the scripts on these projects are right, cameras should roll on X-Men: Apocalypsenext summer.
What's more, while Hugh Jackman may not have much time left on the clock as Wolverine, it sounds like he's got at least one more proper X-Men film in him before the third Wolverinemovie arrives in 2017. You can read more about that over at Collider.
