The Lord of the Rings legend makes his feelings about the popular franchises known during a candid interview with, revealing he took an immediate liking to the first X-Men film script because he identified with the ongoing theme of the series, unlike the storylines in Superman and Bond releases.

MCKellen says, "X-Men was about something. Superman isn't really about anything. It's a joke. The nerd changes his underpants and becomes a Superman.

"That's James Bond: 'Shaken, not stirred', silly, stupid, British twit... and then, Action Man! But X-Men is about the problems of being a mutant. And we've all felt we're mutants on occasion. So, that was the hook for me."

The actor has portrayed the older Magneto in the X-Men films since 2000, and he admits signing on to the first movie wasn't much of a risk for his career, because he only had to commit to the one feature, instead of the multi-picture deals stars have to be locked into nowadays.

He adds, "I didn't have to sign to do anymore than one; I'm just doing a movie. So, it wasn't that big of an adventure. Well, it was a very good job, but I never had to think, 'Oh, do I want to do this for the next 10 years?' It was just a one-off movie."
