I'd probably freak out and start screaming/crying, but i I could get words out I would tell him that he's my idol, my inspiration, and my everything, and that he's changed my life and made me who I am today. then I'd ask for a hug. Yes a hug. It's kind of my goal in life to hug Tim Burton. I was going to try at the Dark Shadows premiere but he didn't sign autographs :P
i would say that your the best director and what was it like to make such weird movies? where do you get your inspirations from for all these wacky roles? i would also say how much the nightmare before christmas is my favorite movie of his!
If I had to meet Tim Burton the first thing I'd tell him is how much I enjoy his movies and love him. I would ask him many questions about his movies and random stuff. I wouldn't want his autograph. I believe the memory of meeting him is more important than a piece of paper and a signature.
