His stories were either pre-written or just improvised.
He’d
traveled a lot, was well read, and watched movies every evening, so it would
be really easy for him to either recall a story, or to come up with a new
one. His stories were fun, filled with love and a sense of humor. He was
a true performer. He acted and created at the same time. He had one problem,
though: he could never remember his stories. Thus, when asked to write a
book with all the improvised stories in it, he had to begin recording himself
on his ever-present – since then – computer. “I am a story
teller, not a computer guy,” George Lucas once said.
