Simon Kinberg, one of the co-writers of "X-Men: The Last Stand", spoke with iF Magazine recently about the "Wolverine" movie and confirmed a few things.

First up, the spin-off's context and character inclusions - ""Wolverine" doesn't exactly come after X3 so what happens to him is not terribly relevant to his own movie. We did talk about a couple of characters that they wanted to save for the "Wolverine" movie spin-off. I can't tell you who they are, but there was really only one we wanted to use for X3, and they said they're not going to have a big enough part to risk losing them for "Wolverine"".

One character making a return though is Sabretooth, Kinberg saying "Sabretooth will be in there, but I don't know in what form. I think his relationship with Wolverine is under explored. I like X1 a great deal, I thought the tone was fantastic and thought the X-Men were great, but I was a little under whelmed by the Brotherhood in that movie. I like working with actors who have inhabited their characters for a while, and I welcome their input. Hugh has lived with Wolverine for five years and he knows this character better than anybody. I would say the most input about Wolverine came from Hugh and not the studio".
