If you woke up today saying "I WISH I COULD SEE A FOUR HOUR BOB DYLAN MOVIE RIGHT NOW", then you are in for a treat. Dangerous Minds just pointed the way to Renaldo and Clara on youtube. If you've never seen this movie, then... well, I can't say you are in for a treat. It feels like a four hour movie. But there's some great live footage here from the Rolling Thunder Review tour.
This copy is much better quality than the bootleg I picked up, so I might end up watching it again.
