Chalamet is an Oscar-nominated movie star known for a slew of acclaimed films, including "Call Me By Your Name," "Lady Bird," "Beautiful Boy," "Little Women," "The French Dispatch," "Dune," and "Dune: Part Two."

And yet, Chalamet recently told Stephen Colbert that "A Complete Unknown" is "the movie I'm proudest of in my career."

Chalamet learned to play guitar for the lead role and sang live during many of the film's musical performances. He said he spent five years familiarizing himself with Dylan's life, discography, and vocal style.

"A Complete Unknown" begins in 1961, when Dylan moved to New York City as a teenager. He released his self-titled debut album in 1962 and quickly became a fixture in the Greenwich Village folk scene, leading many critics to label him "the voice of a generation."

After releasing a few beloved folk albums, Dylan made a divisive pivot toward rock 'n' roll, punctuated with his electric performance at the 1965 Newport Folk Festival. The controversy was documented by Elijah Wald in his 2015 book "Dylan Goes Electric! Newport, Seeger, Dylan, and the Night That Split the Sixties," on which the movie's script is based.

Today, at 83, Dylan is known as one of the most influential and prolific singer-songwriters of all time. He has won 10 Grammys out of 38 nominations, as well as the Recording Academy's Lifetime Achievement Award, which he accepted in 1991.

Barbaro got her start in TV, landing recurring roles in shows like Lifetime's "Unreal," NBC's "Chicago P.D.," and ABC's "Splitting Up Together." She earned her breakthrough movie role as Lt. Natasha "Phoenix" Trace in 2022's "Top Gun: Maverick."

Like Chalamet, Barbaro was not trained as a singer or guitarist before being cast as Joan Baez, who helped Dylan lead the '60s folk revival. She worked with vocal coach Eric Vetro to approximate Baez's famous soprano.

When Barbaro had a chance to speak with Baez over the phone, she said she reassured the musician, "This is all done out of respect."

"She's just like, 'I'm just outside listening to the birds.' She is Joan. She's not so concerned with protecting [her legacy] or hovering over it," Barbaro told The Hollywood Reporter. "She signed over her songs [to the film], all her arrangements. She and Bob are sort of similar, in that they're not so obsessed with dictating this idea of who they are and who they were. They've been in the public eye for so long."

Baez, 83, also received the Recording Academy's Lifetime Achievement Award in 2007. She was inducted into the Rock and Roll Hall of Fame in 2017.

Fanning, who originally costarred with Chalamet in 2019's "A Rainy Day in New York," was a huge Dylan fan before she was cast in "A Complete Unknown."

"I had posters of him on my wall and wrote his name on my hand every day, partly to be cool," Fanning told The Hollywood Reporter. "I worked with ['We Bought a Zoo' director] Cameron Crowe when I was 13, and he played Bob Dylan a lot. He would play 'Buckets of Rain' over and over again. That's when it started."

Fanning's character Sylvie Russo is based on Suze Rotolo, Dylan's girlfriend in the early '60s. She died in 2011.

Rotolo was cemented in music history when she posed arm-in-arm with Dylan for the cover of his sophomore album, 1963's "The Freewheelin' Bob Dylan." She also influenced Dylan's left-wing politics and inspired the song "Don't Think Twice, It's All Right," among others.

According to Fanning, Dylan asked the filmmakers to avoid using Rotolo's real name because she was "a very private person and didn't ask for this life."

"She was obviously someone that was very special and sacred to Bob," Fanning told Rolling Stone.

After Benedict Cumberbatch dropped out of the movie, Norton — renowned for movies like "Fight Club," "Moonrise Kingdom," "Birdman," and "Glass Onion: A Knives Out Mystery" — was hired to portray folk pioneer Pete Seeger.

Seeger's expansive catalog includes the labor-movement anthem "The Hammer Song" and the crossover hit "Goodnight, Irene," both of which Seeger recorded with his folk quartet The Weavers in 1950. He also wrote the patriotic classic "This Land Is Your Land."

Seeger met Dylan in Greenwich Village shortly after the younger singer arrived in town. He is known as one of Dylan's earliest supporters, credited with getting Dylan on the lineup for the Newport Folk Festival. However, according to legend, Seeger was disturbed by Dylan's electric performance at the 1965 edition. Some claim he even tried to cut the sound while Dylan was onstage.

Throughout his life, Seeger was outspoken in support of civil rights, workers' rights, and anti-war efforts, among other causes. He died in 2014 at age 94.

Holbrook is being hailed as a scene-stealer for his performance as Johnny Cash in "A Complete Unknown."

Cash and Dylan officially met at the 1964 Newport Folk Festival, but they had already been exchanging letters as fans of each other's work.

"I had a portable record player that I'd take along on the road, and I'd put on 'The Freewheelin' Bob Dylan' backstage, then go out and do my show, then listen again as soon as I came off," Cash wrote in his autobiography, per Far Out magazine.

"After a while at that, I wrote Bob a letter telling him how much of a fan I was," Cash continued. "He wrote back almost immediately, saying he'd been following my music since 'I Walk the Line,' and so we began a correspondence."

Dylan's manager, Jeff Rosen, gave Mangold, the director, access to letters that Cash and Dylan exchanged in this era. He told Rolling Stone they became "an instrumental voice in the movie."

The two musicians maintained a close friendship until Cash died from complications of diabetes in 2003. He was 71.

You may recognize McNairy from "Argo," "Batman v Superman: Dawn of Justice," or one of two other films released in 2024: "Speak No Evil" and "Nightbitch."

Before the year ends, McNairy will return to the silver screen as Woody Guthrie, widely known as Dylan's personal hero. Guthrie rose to fame in 1940 with his topical album "Dust Bowl Ballads," which chronicles the Great Depression's effects on American Midwesterners. He continued to sing about anti-capitalist and anti-fascist themes throughout his career.

By the time Dylan arrived in New York, Guthrie was being treated in New Jersey for Huntington's disease.

The movie dramatizes their first encounter, including an emotional performance of Dylan's "Song to Woody," with which he serenades Guthrie in the hospital. Chalamet told Rolling Stone that after filming the scene, he went home and "wept." (In reality, Dylan wrote the song after he and Guthrie had already met, per the magazine.)

Guthrie died in 1967 at age 55.

Dan Fogler is best known for the "Harry Potter" spinoff franchise "Fantastic Beasts," in which he played the no-maj character Jacob Kowalski.

In "A Complete Unknown," Fogler portrays Albert Grossman, Dylan's manager from 1962 to 1970. Grossman helped Dylan become an influential figure in the era's folk revival, but his aggressive and intimidating business tactics also earned him a controversial reputation, according to TeachRock.org.

Grossman died in 1986 of a heart attack. He was 59.
