That list doesn't show if those films came in on or under budget, or on time, or if the production looked as good as the money poured into it. McCallum manages to make the movies he's been involved in as a producer look a LOT better than the money typically spent on them, and he gets those movies done fairly quickly and with a minimum of budget overruns. He's a very good organizer. Which is what you want from a producer. Kurtz wasn't as good at that as McCallum or even Kazanjian was.

Kurtz is a good guy, but I've heard he sort of regrets that interview, as he spun it pretty heavy and it made him sound a lot worse than he really meant to. Plus, keep in mind, it's about 5 years old and doesn't take either Episodes II and III into account, which, say what you will about them as movies, DOES help bring out the subtext that IS inherent in Episode I that might not be so apparent to critical viewers when viewed in a vacuum without the other two parts.

But fans have always overestimated his importance to the story elements of Star Wars. they seem to think Producer means co-writer or something, when it's not necessarily the case. It CAN be, but that wasn't Kurtz's role on these movies.
