Timothée Chalamet, who plays Dylan in "A Complete Unknown," said he thought Fanning's experience was either a "great omen" for the film or the "exact opposite."

At just 26, Elle Fanning has Bob Dylan bona fides that belie her age. She was first introduced to Dylan's music by Cameron Crowe on the set of "We Bought a Zoo," and, at 13, became obsessed with all things Dylan.

"A Complete Unknown" director James Mangold said Bob Dylan consulted on his biopic script, but he doesn't know if the singer will see the movie.
