The Hobbit to Be Directed by Guillermo Del Toro, Ian McKellen Confirms
Most interestingly, though, is his answer to the direct question that asks, "Have you been approached yet by Peter Jackson or anyone else about reprising your wonderful role as Gandalf for the two upcoming "Hobbit" movies?"
McKellen answers... "Encouragingly, Peter and Fran Walsh have told me they couldn't imagine The Hobbit without their original Gandalf. Their confidence hasn't yet been confirmed by the director Guillermo del Toro but I am keeping my diary free for 2009!"
What's interesting is the definitive statement that Guillermo del Toro will direct--something that's been strongly hinted at but never formally announced. Pretty much sounds like it's a lock now.
