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.

Bob Dylan's The Very Best Of compilation is soaring on the charts after the success of A Complete Unknown, and it even gives the rocker a new top 10 hit.
