A special effect is a tool, a means of telling a story. A special effect without a story is a pretty boring thing.
George LucasI never had a story for the sequels, for the last trilogy. That's not really part of the plan at this point, and I'll be at the age where to do another trilogy would take 10 years. I'd always envisioned it as six movies. When you see it in six parts you'll understand that it really ends at part six.
George LucasI grew up in the era, 'Don't trust anybody over 30.' And, you know, I still feel that. Don't trust me.
