Richard Williams was the animation director for Who Framed Rodger Rabbit? which wasn't one my favorite films, but I'm really digging cobbler. It's a pretty ambitious film and Williams seems to have a lot of passion for his subject (he spent over 30 years trying finish this thing). Really beautifully designed, great characters, funny, and just generally kind of amazing for a western animated feature. The film's in 17 parts, but apparently a hi-res, whole movie file is floating around on file sharing networks. More information on Cartoon Brew
The Thief and The Cobbler: Recobbled Filmmaker Garrett Gilchrist attempts to contruct of a final cut of Richard Williams epic, unfinished, animation project from a variety of sources that look like film, animatic, pencil tests, and video.
