Lucas as a director reminds me of Anakin's "I will keep people from dying" line.
The shoot for SW was quite troublesome with financial burdens, desert storms wrecking sets, last-minute editing, etc. I appreciate what Lucas went through personally to see that movie completed. Yet, it's as though that experience gave him a deep resolve to never go through a similar process again.
"I will keep people from dealing with movie sets, actors, and other 'cumbersome' filmmaking processes. I will make it all digital!"
