Hugh Jackman Reveals 'X-Men: Days Of Future Past' Secret

'The entire thing is one-shot singing,' the actor joked about involvement in superhero sequel.

Come Christmas Day, Hugh Jackman will join the revolution as convict Jean Valjean in the latest theatrical adaptation of Victor Hugo's classic novel "Les Miserables," but when the actor's finished singing for his supper in 19th-century France, can he be counted on to take up the mutant cause, as well? That's the question swirling around the superhero fandom after reports surfaced last week that Jackman was in talks to reprise his Wolverine role in "X-Men: Days of Future Past."

Original "X-Men" stars Patrick Stewart and Ian McKellan have already signed on for the time-traveling sequel, and with the source comic heavily featuring Jackman's clawed character, the actor's involvement is of particular interest.

Jackman confirmed to MTV News while at a press event for "Les Miserables" that he has indeed discussed the project with director Bryan Singer.

"Yes, I've been talking with Bryan about it," Jackman said. "I did a very small cameo [in 'First Class']. I said, 'As long as it's no longer than three hours [of work] like last time...' "

Whether Jackman will make a cameo or figure prominently into the events of "Days of Future Past," remains to be seen.

"I still have not seen the script, so we're in discussions about [the size of the role]," Jackman continued. "I think things are a little bit in flux and this is my generalized way of saying I'm not going to tell you. Did you buy it? Any of it?"

No, we didn't, Hugh. And we're buying your plot synopsis even less:

"Basically, I'm the only character in it," he joked. "None of the other characters exist. I do talk about them, though. And occasionally you'll see a [thought] bubble, and there'll be pictures of Michael Fassbender and different characters. But the entire thing is one-shot singing, of course. Don't tell anybody that, though. It's really a secret."

"X-Men: Days of Future Past," starring James McAvoy, Jennifer Lawrence and Nicholas Hoult, will hit theaters July 18, 2014.
