While an interesting read to be sure, I think Kurtz should be taken with a grain of salt. Here's his filmography:

5-25-77 (2005) (filming) (producer)
The Steal (1994) (producer)
Slipstream (1989) (producer)
Return to Oz (1985) (executive producer)
The Dark Crystal (1982) (producer)
Star Wars: Episode V - The Empire Strikes Back (1980) (producer)
The Making of 'Star Wars' (1977) (TV) (executive producer)Star Wars (1977) (producer)
Star Wars (1977)(producer)
American Graffiti (1973) (co-producer)
Chandler (1971) (associate producer)
Two-Lane Blacktop (1971) (associate producer)

Not exactly an Oscar winning laundry list, eh? I guess my point is that while his contribution to the saga is indelible, he sometimes comes off as the 'Jesus of Star Wars' which really, really bothers me. I still respect him, but so often he takes the moral high ground like he knows what was best.
