The Bob Dylan biopic ‘A Complete Unknown’ is a remarkable telling of the rise to fame of the legendary Bob Dylan but like all movies based on real life, liberties were taken to fit the story into one two-hour and 20-minute capsule.

It might at first seem obvious why filmmakers won’t leave the subject of Bob Dylan alone. Search “Dylan” and “movies,” and the list — from documentaries like “Don’t Look Back” (1967) to fictionalized treatments like “I’m Not There” (2007) — turns out to be surprisingly extensive.
