I ran across the video off Youtube about underground cartoonist Robert Crumb. If you've seen the first film, Crumb by Terry Zwigoff, this makes a nice addition to that one, although they cover much of the same territory. I have the Crumb film on the standard DVD release only, and I know that Criterion has released it as well. It may be on Blu-ray as well, I don't have that format either. Either way, some might want to check this out if you've not seen it before.
