George Lucas: Maker of Films

Not 100% sure if this is the right place to go, but here it is:

I'm looking for a documentary/interview done on George Lucas following his debut of THX 1138. It was done in 1971, and the interview was made by film theorist/critic Gene Youngblood.

Not only does it talk about Lucas' work with THX 1138, but I hear there's some question that goes along the lines of "so what's this movie idea I hear of a war in the stars?"

Any references would be greatly appreciated.

 

I don't know anything about that.
The only interviews that I've seen from that time are the ones on the THX 1138 DVD.
