'Amadeus', Bull Durham' and 'ILD'
Proposed sequel (Coen Bros., I can be bought):
I read Dave Van Ronk's memoir and something occurred to me (and, yes, I know that LD is only a little bit VR, a little bit Sisyphus and maybe a Coen brother or two).
Like Salieri in 'Amadeus' and "Crash" Davis in 'Bull Durham' ("Davis"? Coincidence? Probably), Van Ronk was the established craftsman confronted and superseded by out-of-left-field genius (Mozart, "Nuke" Laloosh, Dylan). Llewyn (the character) is not the eminence grise that the others were but there's still a sense of the inescapable difference between talent and genius.
