HitFix (via CBM) has confirmation from Darren Aronofsky that he is indeed directing Wolverine 2 now titled just The Wolverine. He goes on to state the film has no ties to the other film (hence no Origins/X-Men in the title) and isn't a straight up sequel. Also there is talk that Darren's longtime cinematographer Matthew Libatique will also be working on the film. Libatique is known for his beyond stylish way of shooting. He's shot such amazing looking films like Pi, Requiem For A Dream, The Fountain, Black Swan, Tigerland, Iron Man 1-2 and Cowboys & Aliens. There is a certain confidence this film along with First Class could help turn around the tarnished X-Men franchises.
"The film that he's directing is officially called "The Wolverine," and there won't be a number attached to it. In our interview, he referred to the movie as a "one-off," and he emphasized that the film isn't a sequel in any conventional sense."
