Nailed it.

Timothée Chalamet’s lauded transformation into rock icon Bob Dylan in “A Complete Unknown” was so complete, it went all the way down to his cuticles.

The “Dune 2” actor, 28, ended rampant speculation about whether the surprisingly long fingernails he has in the new biopic (out Dec. 25) are actually his own during an interview with Fandango.

In a short clip from the sit-down shared on TikTok, the star spoke about his talons after the interviewer brought up the movie’s evident attention to detail, which includes dirt under the actor’s fingernails.

“He did have them,” Chalamet’s co-star Elle Fanning, who plays Sylvie Russo, a character loosely based on Dylan’s girlfriend in the early 1960s, Suze Rotolo, said of the actor.

Chalamet “had to grow them out,” she added.

The “Call Me By Your Name” actor then chimed in, sharing that his nails “got stronger over time.”

“They would chip at first. That must be some bodily process, like your body just gets used to,” he trailed off and then added, “by the end they were like claws.”

James Mangold, who directed “A Complete Unknown,” also spoke about Chalamet’s nails, even comparing them to those of a vampire.

“Yeah, he was growing them. 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,” he told Business Insider in a Dec. 19 interview, referring to the new remake of the 1922 vampire movie.

Chalamet’s nails have been intensely scrutinized online.

“Did Bob Dylan have crusty long nails?” an AI narrator asks in a TikTok video showing photos of Chalamet’s prominent claws during the filming of the Dylan flick. The video has been viewed over 870,000 times.

Dylan has in fact worn his nails very long but the singer-songwriter has never gone on the record to explain why. Some have pointed out that the long fingernails might be helpful when playing the guitar.

Nails aside, Chalamet was committed in other ways to making his portrayal of Dylan as spot-on as possible, even wearing a subtle nose prosthetic and different length sideburns to indicate the passing of time.

He also dedicated himself to mastering the art of playing the guitar and the harmonica and trained his voice to imitate Dylan’s distinctive singing style.

As he’s gone about promoting the film, the Oscar nominee has been careful how speaks about his performance and what he reveals.

“The whole thing was really just a sort of magical experience,” he recently told People. “I don’t want to ruin it with words because, really, it’s deeply personal to me. I can say just being in that time period was awesome, and living that.”
