Les Misérables star Hugh Jackman has said that his character is "vulnerable in every way" in new movie The Wolverine.

The 44-year-old actor reprises his role as the superhero for the upcoming X-Men spin-off and said that it involves a much deeper exploration of his character than in the previous movies.

Speaking to SFX magazine, Jackman said: ''In this story, he becomes literally vulnerable in every way. Not just emotionally, but physically vulnerable, and those implications were fun to play.''

The Wolverine takes place after the events of 2006's X-Men: The Last Stand and sees Jackman's character isolate himself in Japan as he grieves the death of close friends and his love interest, Jean Grey (Famke Janssen).

Jackman added: ''You see Logan [Wolverine] at his lowest point at the beginning of this movie; the tragedy of his wasted life. For the sake of not only himself but everyone around him, he thinks it's better to be away because when he comes back to the world, there's destruction and pain.''

The Wolverine opens in cinemas on Thursday July 25.
