The filmmaker revealed that he hasn't ruled out an appearance by the Oscar-winning actress yet but is deciding how her character Storm would fit into the story of the second film, Days Of Future Past.
"I can't say. I don't know yet. And it's not necessarily a deal making aspect at all. I want to make sure it'll make sense. But I love working with her. Each character has a very important function in the story," he told MTV News.
Sir Ian McKellen, Sir Patrick Stewart, Hugh Jackman, Ellen Page, Anna Paquin and Shawn Ashmore are set to reprise their X-Men characters, alongside returning stars James McAvoy and Michael Fassbender.
Bryan, who directed X-Men and X2, revealed he may use his new knowledge of computer-generated technology from his film Jack The Giant Slayer in the next instalment in the X-Men franchise, which will involve time-travel.
"I definitely want to use this technology again, and I might even be using some of it in a different way in X-Men. I don't want to say how, yet, but I'm definitely using some of this technology on X-Men, which I never used in any of the other X-Men films," he said.
X-Men: Days Of Future Past is due to start shooting in April, for a 2014 release.
