If Dylan Had Done His "Fictional" Film
I suspect it would have ended up quite a bit like Who Killed John O'Neill. This film is very reminiscent of "A Beautiful Mind" complete with the conspiracy theory diagrammed on the wall:
I could only watch about 15 minutes of the movie before I got a headache. It's arty to the max, almost completely black and white, with lots of shouting. It seems almost like it was shot using madmen as actors (actually there appears to be only one actor, although he plays several different roles).
