I said to George that I wanted to go back to the way it was, in the sense that ours was much more carefree and lighthearted and humorous – in my opinion, anyway....hope they find the right balance of CGI with practical effects. I love props, I love models, miniatures, matte paintings -- I'm sort of old school. I think if you go too far in the direction of CGI it winds up looking like just a giant a video game, and that's unfortunate. … If they listen to me at all, it'll be, 'Lighten up and go retro with the way it looks.'

It's good to know that he thinks like we do.
