FROM SPLASH PAGE: Given recent comments from Sir Ian McKellen about his involvement (or lack thereof) in the upcoming "X-Men Origins: Magneto" film from Fox, it's time to face the inevitable—Magneto is going to be recast. This was already a virtual certainty due to the story's purported focus on the Master of Magnetism's more youthful days, but McKellen's words confirm the need for a new, younger actor.
Recasting Magneto is difficult for a number of reasons. For one, McKellen already played him so expertly that an actor of his quality is absolutely essential—and not only that, but it'd be a good idea to find someone who looks like they could age into McKellen's likeness, which is very tricky. For that reason, I think it's more important to focus on finding an excellent, fitting actor for the role, rather than selecting an actor based on his likeness to McKellen.
When and if "X-Men Origins: Magneto" gets underway, I think any one of these five actors has what it takes to bring the magnetically-inclined mutant back to the big screen.
