If you're interested in European/indie comix, there are some interviews from a French tv show available on-line (some mostly in English). There is also a bit torrent download available with an interview with Chris Ware from the same show but different source.
Can't comment on them since I'm still downloading the Ware torrent. Oh, dial-up!
French television channel 'Arte TV' has been running a series of behind-the-scenes documentaries on various Comic Book creators throughout the month of January. One of these episodes focuses exclusively on Chris Ware. The website for the series has video clips of every episode BUT Ware's, though they do offer a nice original flash animation of bits from Jimmy Corrigan (This is not the same animation as the one on the Pantheon site). Anyone who reads this site knows that I have an unhealthy obsession with the work of Mr. Ware, so it should come as no surprise that I've managed to obtain a copy of the episode in question.
