The Wolverine is one of the most highly-anticipated movies this summer, with Hugh Jackman returning as Logan. Director James Mangold revealed that the title character is much more intense, bringing back the 'berserker rage,' which fuels Logan's journey.

"The whole point is not about violence or rating; it's about intensity. I wanted to make a film that in a way captures the intensity of his character. One of the things that has always been a feature of Wolverine in the comics is that he has a berserker rage, that he has anger and some of his abilities are driven by something more primal. Honestly, to get really pissed off - not cute pissed off, not quippy pissed off, not funny pissed off or cigar-chomping pissed off, just pissed off - that can then help drive the fighting, drive the combat. That is interesting for me and then for the character, some of the jet fuel underneath some of the combat in the film."

The filmmaker also revealed that he wants The Wolverine to stand alone from the previous movies, giving Hugh Jackman a different look and setting almost the entire movie in Japan.

""We've given Logan a new haircut, a shorter haircut that I think is a more handsome haircut. The wonderful opportunity for me with this film is that 90 percent of it takes place in Japan, and even though other elements remain constant from the other pictures, namely Hugh Jackman, we kind of got our chance to reboot the tone and go a little darker and a little deeper than they've gone before with this character. That was exciting for me."

James Mangold went on to say that the movie features a "cross-pollination" of a Western character in an Eastern culture.

"There is a significant amount of Japanese spoken in the movie, and the cast is almost entirely Japanese. So there is this wonderful sense of cross-pollination between a very Western character and a far Eastern culture, and I think it's very cool and something we haven't seen so far. I think there is a lot of ways that Japanese film, Japanese fighting, Japanese martial arts have had an effect on this movie. And certainly the movie is dripping with Japanese tradition both cinematically, fighting-wise and philosophically as well."

He also revealed that a new trailer is "coming soon," although he wouldn't reveal an exact date. He did say that he prefers a "less is more" approach to the marketing.

"I think you always want to put your best foot forward. For me, I'm not the marketing department of Fox, but for my own tastes, less is more. You have a character that's a bit of a given, you know this guy. Hugh is so good in this role. My point of view is 'save as much as you can,' but we will be lifting our skirt and offering a peek or two, certainly in the months to come."
