As we revealed before, this movie will be set after the previous X-Men films to set it apart and put Wolverine in a different world so to speak, where the other heroes are gone.
Action is to be more grounded and realistic this time around.
Hugh Jackman never felt like he had time to get in the shape he wanted in previous films for the character and this time around he even called Dwayne "The Rock" Johnson for some tips about getting into shape.
This movie is going to focus on the fact that Wolverine is essentially immortal and the curse that can come with living forever. Though we will learn what Wolverine's "Kryptonite" is.
