Hummm, the 'Richard L. Anderson' and 'Kathryn Farrar' added in the SE later variation, are not in the 2011 set where they showed up before. But haven't done a complete check, maybe they just got moved...
Anderson: http://www.imdb.com/name/nm0027328/
Farrar: http://www.imdb.com/name/nm0268133/
Maybe all these uncredited SW people would make for a nice SaveStarWars article.
