I didn't realize different areas had different interviews. That's pretty cool, though like you say, people won't see all of them. :p Any idea how many there are total? I bet when it's all done, they'll make some sort of box set, but they always charge HUGE prices for stuff at PBS.
It was actually on one of the PBSs a couple of weeks ago, then last night, both an hour long. (actually, it went around an hour and three minutes, and I almost didn't catch that)
