At the end of The Wolverine, the title character was left with only bone claws after his metal ones were sliced off by The Silver Samurai. For those of you who have been paying attention to the footage and photos from X-Men: Days of Future Past, you may have noticed that modern-day/future Wolverine appears to have regained his adamantium claws. In case you were wondering how that happened, Bryan Singer gives a possible explanation in his interview with Empire.
Director Bryan Singer explains that Magneto’s ability to manipulate metal might have something to do with it. The Master Of Magnetism could, perhaps, “reconstitute the adamantium claws… [Wolverine] has a different relationship with Magneto, and perhaps Magneto could forge them.”
I hope they give a solid explanation of all this in the movie, and not some thoughtless piece of dialogue about Magneto fixing them. I think the audience and fans deserve to see how it all happens, and maybe Singer will actually give that to us!
