Don't worry he won't get far on foot

Amazon has a film about John Callahan, whose over the top cartoons made him a legend among the disability activist community.

no, I haven't seen the film, so don't know if it is good technically (or accurate medically), but the reviews seem to pick at it for the obvious trivial issues (he was obnoxious alcoholic, he had issues, and one was furious because he got cured via AA).
