"I know it seems odd given, you know, the guy is already half animal," says Hugh Jackman, who revives the character in Wolverine, due in theaters May 1, 2009. "But with all the success of the X-Men, you feel the pressure to keep pushing it further."
According to USA Today, the film will trace Wolverine's past as he discovers the world of mutants and, ultimately, the ominous Weapon X program, which turns people into living weapons.
Jackman is tight-lipped on plot details, though he says the film will hardly be a one-mutant story.
Wolverine's nemesis Sabretooth "is going to play a big part in it. And there will be a good bit of cameos" of new and familiar mutants, he says. "But you can't give too much away, because fans are pretty hard-core. Their expectations go up a level every time you come out with a new film."
