Well, this isn't good. It seems that the start of The Hobbit has been delayed for so long in its search for a director that it's starting to affect the talent's schedules. Luckily, all of the talent is debatably replaceable, with one glaring exception: Ian McKellen, who absolutely must play Gandalf the Grey. Or must he? McKellen has a potential scheduling conflict and may have to drop out, which sounds devastating, but while Gandalf does not age as men do, and should therefore look more or less the same as he does 60 years later (when The Fellowship of the Ring occurs), isn't a little creative license a good thing? Couldn't a new Gandalf help to differentiate these films from the original trilogy? Nobody wants to see McKellen replaced, but it's better than another delay or even the death of the film, so here are some suggestions for actors to play the original sorcerer supreme.
