If you're not a comic fan who suffered through the 1990s you might not know that Wolverine has bone claws. See, in the X-Men crossover comic series Fatal Attraction, Magneto finally did something that he should have done years earlier - he tore the adamantium off of Wolverine's bones. You might think this would leave Wolverine clawless, as it seemed (and had really been completely previously established) that the claws were mechanisms within his forearm. You'd be wrong! It was quickly revealed that Wolverine had been born with retractable bone claws!
It's as dumb as it sounds. Maybe even dumber. And now it's coming to the movies, as The Wolverine will feature Logan with bone claws. But here's what I can't figure: how? See, director James Mangold tells Empire:
"Where this film sits in the universe of the films is after them all... Jean Grey is gone, most of the X-Men are disbanded or gone, so there’s a tremendous sense of isolation for him."
I suspect that he's semi-fibbing. At the very least portions of this film will be flashbacks; the recent rumors about Jean Grey being in the picture and the image of Wolvie with bone claws all but guarantee this. This film may take place after the events of X-Men: The Last Stand, but it will surely feature events that happen even before X-Men Origins: Wolverine.
