Whilst this week's Marvel comic adaptation "Iron Man" is making a big selling point of it being more comical and light than your average superhero, next May's superhero movie is expected to be a whole lot darker.

Tonally, I would put it more in the 'Batman Begins' sort of realm. That's sort of where we're headed" Hugh Jackman told MTV News when speaking of "X-Men Origins: Wolverine" which he is currently filming for release May 9th 2009. Liev Schreiber, Dominic Monaghan and Ryan Reynolds co-star.

"We are dealing with a character who is probably one of the darker comic book characters ever created. The movie has a lot of fun elements, but there are layers of pain and darkness to this character" he adds.

Would he come back for further sequels? "I really wanted to do this spin-off movie, because I felt we hadn't truly found who this character was. Right now. I feel like I could do another ten or eleven."
