"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."

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.

He respects the reclusive legacy of Bob Dylan while also delivering on one heck of a show that will perhaps inspire a newfound interest in the folk genre and how Dylan came in “like a rolling stone” to shake the whole scene up by going electric.

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.
