And I would choose none of the above!

I don't think Dylan consciously constructed his persona to be like any one person in particular. But he was a student of a lot of people who did that sort of thing, Niles being but one. Woody was another. The Beat poets he was surrounded by another influence. Sam Shepard, a theatrical influence that obviously hit Dylan where he lived. Which begs the question: why no mention of Shepard in the documentary either? Shepard was likely one of the stronger absurdist influences on Dylan, and they seem to have maintained this odd relationship over the years, which began when they were both young pups living in the Village.
