He’s no stranger to interviewing big stars as a host on BBC Radio 2.

But even Vernon Kay struggled to hide his excitement as he watched Timothee Chalamet casually arrive for the premiere of his Bob Dylan biopic A Complete Unknown on Tuesday.

The presenter, 50, was seen filming the actor as he cruised down the red carpet on a Lime Bike.

Vernon was among several stars who joined A Complete Unknown’s cast on the red carpet at the BFI Southbank, including Laura Whitmore and Paul Mescal’s sister Nell.

Timothee walked the red carpet solo, with his girlfriend Kylie Jenner deciding to stay home. The A-list couple have largely kept their two year romance out of the spotlight.

Monica Barbaro, who stars in the film alongside Timothee and Elle Fanning – who was a no show at the UK premiere – made sure all eyes were on her at the event.

The movie focuses on Dylan’s early career, his transition from folk to rock, and his performance at the 1965 Newport Folk Festival, with Timothée being praised for his portrayal.

It comes after Timothée revealed he had ‘five years of singing practice’ ahead of his role as Bob Dylan in the upcoming biopic, A Complete Unknown.

The actor, 28, who stars as the Knockin’ On Heaven’s Door hitmaker, 83, both sings and plays the songs live in the drama which is set for release in January.

Appearing on The Graham Norton Show on Friday, he admitted to not knowing much about Bob before, but is now ‘deeply pᴀssionate’ about his cultural impact.

Timothée said: ‘I had a lot of time to practice because we were meant to make the film five and half years ago, then there was Covid and then there was the actors’ strike, so I have years to prepare.

‘I was confident about singing and by the time we got to do the film I wanted to sing and play the songs live.’

He added: ‘I didn’t know much about Dylan but now, having worked on it for so long, I really worship at the church of Bob.

‘I am deeply pᴀssionate about this man and his work. My friends are tired of hearing me talk about him ad nauseam.

The Oscar nominee, who did not have any face time with the hitmaker prior to playing him, has been praised by critics for saving the film, despite its flaws.

Timothée continued: ‘Bob is an elusive, mysterious figure and a man of few words so I never got the chance to meet him.

‘I would like to, but I am very respectful that it is true to his character that I would never get to meet him.’

Elle Fanning will star as Sylvie Russo, a renamed version of Bob’s girlfriend from the time while Monica Barbaro will play Joan Baez.

The movie centres on the singer-songwriter’s controversial switch to electric instruments at the Newport Folk Festival in 1965.

Timothée – who will be joined in the cast by Edward Norton and Boyd Holbrook – was confirmed to be doing his own singing in the movie after lending his vocals to his 2023 musical flick Wonka.

Director James Mangold confirmed that he has been working with Bob on the project and that the Hurricane singer had some personal input into the screenplay.
