Still, if "Magneto" does make its way to theaters within the next couple of years, it's unlikely that actor Ian McKellen will assume the magnetic mutant's mantle for a fourth time, if only because nobody has supplied him with a screenplay yet.
"There's meant to be a 'Magneto' script floating around," McKellen told Empire Online. "[But] I've not read it, so I suspect it wouldn't involve me."
The acclaimed "X-Men" and "Lord of the Rings" actor acknowledged the already well-publicized idea that "Magneto" would focus on the mankind-hating mutant as a youth, meaning that McKellen's involvement in the project is probably unnecessary.
"I think it would be about the younger Magneto, and the most I could hope for would be to top and tail that," said the actor. "They can't have someone whose face is as lined as mine any longer!"
Sure enough, McKellen and Patrick Stewart were aged down in "X-Men: The Last Stand" thanks to the wonders of modern CGI effects, but that was just a fleeting scene—a whole movie with that technology in effect would be very hard to pull off.
But the actor isn't ruling out a cameo return for "Magneto," particular because Stewart's recent appearance in "X-Men Origins: Wolverine" was such a hit.
"Ooh, he was very pleased with himself that he was going in to be in 'Wolverine,'" McKellen said. "It was only an hour's work!"
Should McKellen be involved in "X-Men Origins: Magneto" in some capacity, or would you rather see the movie feature a different actor as the Master of Magnetism? Let us know in the comments section!
