There is a dvd out with three of Lucas student films.
THX 1138:4EB Electronic Labyrinth
A man and his car
and freiheit.
The dvd also has other directors student films. I can't remember the dvd name off the top of my head. It was also sponsored by USC School of Cinema. Not a surprise. Without Lucas generous donating where would that school be.
The most genious part of the student version and film version of thx 1138 are the sound design by Walter Murch.
I think the first Lucas film to be shot in widescreen was called Anyone lived in a pretty how town. I have only seen clips. The whole thing has not been released. Neither has his Mckenna's gold tone poem.
For years it was impossible to find his documentary on the rainpeople until someone posted a fairly good quality copy online. I have a very bad version which looks like someone played the film and videotaped it off of a screen.
And once George Lucas maker of films gets released as a fan preservation by one of the members of these board there will be less stuff to have to have an impossible time unearthing.
If people are fascinated by Lucas i recommend purchasing a copy of the book the george lucas interviews, and the book skywalking by dale pollock.
There is also a fairly good early article and short one on Lucas in the book the movie brats.
There is no book that offers an unbiased chronologic view of Lucas filmaking career. The single book out is an authorized one and therefore suspect of being biased towards modern Lucas in a positive way. I have that book by Rinzler and despite some nice pictures it is mostly pre digisted information from lucas video interviews and articles and is purely garbage and spin.
I would like a book that traced all Lucas films from his college days to now based on their thematic ideas and interconnecting threads, and also where Lucas fits in in the french new wave of cinema verite and auteur theory of filmaking. Pure Visual filmaking without story.
I found it somewhat terrorfying the modern lucas school of thought on making movies is taught at all in filmschool, cgi over subtance. I'm happy there are some schools that actual teach how to handle and shoot real film and not just HD video edited on a computer.
