THE force behind the X-Men: Days of Future Past -- currently dominating the Australian box office -- has confirmed he will push to use the same cast for the upcoming X-men: Apocalypse.
Writer and producer Simon Kinberg has also said how "awesome" it would be for Wolverine to one day battle Iron Man alter-ego Tony Stark.
A very brief teaser trailer for Apocalypse runs after the credits of Days of Future Past, showing a figure manipulating a historic landmark while an army of worshippers chant unintelligibly.
Kinberg told American magazine The Daily Beast the sequel will ideally lock up the same cast from Future Past and its predecessor First Class, with a smattering of those from the original trilogy.
"It will focus primarily on the First Class cast, but it will certainly have some of the original cast involved, too," Kinberg said.
The original cast included Halle Berry as Storm and Anna Paquin as Rogue.
Kinberg is asked if the X-men "universe" could ever collide with other worlds, including those featuring Captain America, Thor or even Spider-Man.
"As a fan I would love it," he said.
"I would love to see the movies be able to do everything the comics would be able to do.
"In the real world, people don't really understand that certain characters are licenced to certain studios - that Spider-Man is controlled by Sony, X-Men by Fox, the Marvel characters by Marvel and Disney.
"There are enough characters within each of these separate universes, but listen: a scene between Wolverine and Tony Stark would be awesome.
"It would be incredible.
"But for now, you get awesome scenes between Tony Stark, Captain America, and Thor, and you get awesome scenes between Wolverine, Charles Xavier, and Magneto."
Director Bryan Singer is still Kinberg's choice to direct Armageddon, despite Singer facing a suit for allegedly sexually abusing a teenager in 1999.
