THR reports that Christopher McQuarrie will write the script for the upcoming sequel to X-Men Origins: Wolverine. McQuarrie will be responsible for adapting the storyline from the 1982 Wolverine comic book mini-series by Chris Claremont and Frank Miller that was hinted at briefly in a post-credits sequence in Wolverine. McQuarrie is no stranger to the X-Men universe, having done an uncredited re-write on 2000's X-Men.
Hugh Jackman has been staunchly in favor of the Japan storyline since the subject of a Wolverine sequel was raised, and promises that Wolverine 2 will be "fairly faithful" to the Miller-Clarmont book, though Jackmand says they will have to "pick and choose" portions of the story to cover.
[Wolverine 2] will be very different from the last Wolverine movie, and that's what I like about it. I didn't want it to feel like the same thing.... It's a whole new environment and the storyline is unbelievable. Like all the Wolverine and X-Men stories, they're long. If you put together all the Japan saga stories, it's so long.
One way Wolverine 2 will be like its predeccessor is in its supporting cast. "There will be a lot of new mutants," said Jackman. However, if Wolverine 2 stays faithful to the comics, Jackman claims that it will also be a much steamier Wolverine than before.
Parts of that story were pretty dark. I don't know if it's the darkest, but I'm going to go out on a limb right now and say I think it will be the sexiest. There's some female companionship — and not just one — for Wolverine.... My wife might have an issue with it, but I think the fans will like it.
Jackman says that Wolverine 2 can be expected to reach theaters in 2012. "If you look at the history [of the X-Men movies], it's been every three years — three years exactly."
