Fantasy usually attracts people whose imaginations are way more interesting than real life. Far from being eccentric, there is virtue in the way they spin together entire worlds out of pure ideas. It’s a quality that The Hobbit director Guillermo del Toro has in abundance, which Ian McKellen discussed with Empire, along with the progress of the script:
“The scripts for the two films will be delivered very soon,” he revealed. “Then they’ll be budgeted, and then they’ll be cast. And they’ll be going when they’ve always said they would be, which is next spring – March or April. Guillermo even told me at one point, ‘We’re going to film for 383 days.’ He’s got that artistic autism! Jackson’s the same; they’re very, very, very alike. They also very different, but they’ve so much in common. They both can’t stand Hollywood and have wonderful imaginations, and they’re both obsessed with gore and fantasy. Both of them laugh a great deal. Guillermo’s one of the most brilliant men I’ve ever met. His English vocabulary is way superior to mine!”
Never trust a mirth-full man who enjoys violence. Hiring him to direct The Hobbit was a brilliant move; he can do both dark fantasy and light-hearted fantasy well. Anyway, you can read the rest of McKellen’s thoughts, as well as his participation in the Magneto origin story (he is uninvolved at this point), at the link.
