The making of star wars, based on the unpublished work of Charlie Lippincott.

Rinzler edited it for publication. He may have authored the book but the raw interviews and accounts of the making from 1976 on was done by Charlie.

One of the unsung heroes of star wars success, he was there in 1976 at the world science fiction convention to promote the film.

I still think Charles Lippincott deserved a co author credit.

Its like Lucas taking credit for the authorship of the star wars trilogy. When other people wrote them.
