“I can guarantee you there are going to be surprises. David Benioff, who wrote the script, is one of the great writers in Hollywood, and he is the biggest comic book fan in the history of the world. There is not an issue of Wolverine or X-Men that he doesn’t own.

When he first pitched me the idea, he had such a brilliant idea that was his little twist on events. He’s written it smartly. He knows what the fans want.”
Hugh Jackman

Saying about the sequels story:

“The most intriguing thing to me was the Japan story. I love the Japan story. I wanted to do the Japan story from around X-Men 2. Can you just picture Wolverine in Japan with the triads and the samurai? It’s just genius. Comedically and dramatically, I thought, ‘This is awesome!’ But how can you do that before you explain his origins? If we tried to mix the origin and Japan together, it wouldn’t do justice to either. So you can tell by the answer where I’d like it to go.”
