All good things must come to an end, and it would seem that "X-Men" stars Jennifer Lawrence and Nicholas Hoult have reached that point with the franchise. But what of Michael Fassbender, who has played Magneto in "X-Men: Days of Future Past" and "X-Men: First Class"? Will his turn in the helmet in "X-Men: Apocalypse" be his last?

While promoting "Slow West," the new Western Fassbender stars in alongside Kodi Smit-McPhee, we asked whether he'll also be making his exit from the franchise.

"I'm not sure," he told MTV News. "I presume [Lawrence and Hoult] are talking about contractually. All of us signed on for a three-film deal, so we'll just wait and see what happens after this."

But would he be game for another turn in the role, if it was possible? "Always interested in moving forward," he said.

Last month, Lawrence confirmed to us that "Apocalypse" would be her last time in the blue body paint, saying "it is my last one." Nicholas Hoult was less clear, telling us that "it is the last contracted one for now."

Fassbender's "Slow West" co-star, Kodi Smit-McPhee, will also appear in "X-Men: Apocalypse" as Nightcrawler.

"Slow West" hits theaters and On-Demand May 15.
