It takes all of a few seconds of Hugh Jackman discussing "The Wolverine" to see just how passionate the actor is about his alternate mutant persona. With the latest movie to feature the Marvel fan favorite, Jackman is exploring a deeper, much more personal side of Wolverine than we've ever seen before.

The story of Wolverine's exploits in Japan has long been one revered by Jackman and fans alike. "It's dear to their hearts. It's one of the most intriguing, interesting, and actually one of the most dominant parts of the comic book lore, Wolverine in Japan or the Japanese Saga or the Samurai Saga, it's been called," Jackman said. "I think it is, from the very first 'X-Men' movie I did in 1999, I saw this comic book and I remember saying to Lauren Shuler Donner, our producer, 'This is a great movie.' "

So when Jackman sat down exclusively with MTV News' Josh Horowitz to discuss the first trailer for "The Wolverine," which premiered Wednesday, he could barely contain his excitement for the new movie, its big action scenes and the new characters that pop up.

On Viper

"Viper is a badass, for someone who plays Wolverine, who is pretty badass. ... She's not your girl next door. You're going to end up kind of loving every minute she has on screen."

On the Bullet Train Sequence

"It is insane. It was insane to shoot it. It was, again, one of those brilliant ideas. One of the most emblematic things about Japan is the bullet train. I can't go on the bullet train without any incident. It was hairy, shooting that stuff. To re-create what that is like, the kind of winds at 300 miles per hour, let me just say, looking back at some of the footage, I thought, 'It's time for a facelift.' "

On Jean Grey

"There's no doubt that the most important relationship in his life is -- we've seen through the movies -- is his relationship with Jean Grey. Yes, we saw her die at the end of 'X-Men: The Last Stand,' but in this movie, she has a presence, which I think is vital to the movie, particularly for him confronting the most difficult thing within himself."
