I remember having to do this in school once. Our teacher taught us how to write to celebrities to get autographs. I wond up writting to George Lucas and Dusty Baker when we had to choose a sports one. Neither letter got sent though through my own fault.

I'd ask something like, "How has your vision for Star Wars changed over the years? What influences these changes?"

Ric's second one is really good, as is rebels.

"Do you find that having the freedom technology gives you has any negative impact as well as the positives?" Something to that nature.
