Never let it be said that Timothée Chalamet doesn’t do his homework. In his first extensive interview about his role as Bob Dylan in the upcoming biopic A Complete Unknown, the Willy Wonka star told Apple Music’s Zane Lowe that he learned how to play 13 classic Dylan songs for the movie, in addition to working with a harmonica coach for five years to nail the Rock and Roll Hall of Famer’s signature style.

In addition to tapping a movement coach to help him embody the enigmatic icon’s physical stance, Chalamet also told Lowe that he took a “spirit-gathering” road trip mimicking the Minnesota native’s early years as a budding folk singer, starting off in Dylan’s hometown of Hibbing, MN, before traveling to neighboring Duluth, then on to Chicago and Madison, WI.

“It was the best experience I’ve had as an actor or the most rewarding experience I’ve had doesn’t really necessarily translate to the effect of it, not only on people, but maybe in the finished product because I’ve also had more challenging experiences that come out great,” Chalamet said of the long journey to bring the singer to life on screen. “I’m happy it took five, six years because I am now deep in that Church of Bob. I feel like that’s my mission is the next three months, until the movie comes out, I feel like I’m in the Church of Bob, I’m a humble disciple, and I feel like I got this opportunity to kind of be a bridge to this music or this period, this time period.”

Despite his deep-dive, Chalamet said he wasn’t trying to do an imitation of the singer’s voice, explaining, “This is interpretive. This is not definitive. This is not fact. This is not how it happened. This is a fable.” In fact, he said none of his fellow actors were there to perform impersonations.

“This is about not only myself interpreting Bob, but Edward Norton interpreting Pete Seeger, Monica [Barbaro] interpreting Joan Baez and Boyd Holbrook interpreting Johnny Cash in this moment in the ’60s where American culture was a kaleidoscope and Greenwich Village was a kaleidoscope,” he said. “The way culture still is now too, but without being a history teacher, that was the beginning, personalized music, stuff with intention, stuff with poetry, it all started there in the movie.”

The journey was, as expected, arduous, given Dylan’s unique vocal style and quixotic public persona. Though he said he didn’t play guitar on the pre-records of the songs, Chalamet said he worried the guitar on the songs was too “friendly,” given that in the early 1960s Dylan was playing an instrument was “basically falling apart.” Similarly, the actor said he found that his voice had a baritone range, but that too sounded too “clean” too him.

“I was doing vocal warmups with Eric Vetro, who was this vocal coach who helped me on Wonka and helped me sing ‘Grand’ on Wonka. And then, here, I would listen to it back and I’m like, ‘Man, this sounds too clean,’” he said, calling the role the “most dignified work” he’s ever done.

In a nod to Dylan’s often unpredictable nature, Chalamet recalled that the singer’s manager secretly came to set one day and after watching the actor he praised him for capturing the “spirit” of his client. In fact, the text he got was so effusive and positive, that Chalamet said he and Norton were “jumping up and down and went, ‘man, Bob’s manager loves it’ and then we were like, ‘oh no, the real Bob’s such a contrarian that Jeff’s gonna go to him and say this movie looks good and then Bob’s gonna say well, it must be a piece of s–t.’”

Now that he’s been fully immersed in the “Church of Bob,” Chalamet said he feels like he can be a “bridge” to bring the the voice of a generation to a whole new generation. In a pair of trailers to date, Chalamet appears to fully transform his voice and physical manner to tell the story of Dylan’s early 1960s rise to fame and the controversial moment he switched to electric guitar at the 1965 Newport Folk Festival.

A Complete Unknown opens in theaters on Dec. 25.
