"Yeah, he was growing them," "A Complete Unknown" director James Mangold told Business Insider. "If you look earlier in the movie, there are some scenes where they aren't as long, but by the end, he had some full-on Nosferatu going on."

A Complete Unknown” certainly lives up to its title. You are hardly closer to understanding the soul of Bob Dylan after watching more than two hours of this moody look at America’s most enigmatic troubadour.

Dylan, a Nobel Prize winning poet, songwriter and performer, also ranks among the most enigmatic. Mangold chronicles Dylan’s Greenwich Village roots, performing in basement coffee houses, recording, forming a romantic and professional partnership with folk singer activist Joan Baez.

Despite the film being utterly conventional, Timothée Chalamet, whose range and confidence keep growing broader, is sensational as Bob Dylan, writes the reviewer.

Timothée Chalamet and Edward Norton explain why they still don't know Bob Dylan after making the biopic "A Complete Unknown," in theaters Wednesday, and why that's a good thing.
