There's just a few months to go until 'Wonka' is released, and director Paul King is certainly putting the hard sell on.

Timothee Chalamet is set to star as the titular chocolatier in the Willy Wonka origin story based on Roald Dahl's 'Charlie and the Chocolate Factory', while he will also perform some songs in the film.

The original music was written by none other than Neil Hannon of The Divine Comedy, while King has likened Chalamet's voice to that of the legendary Bing Crosby.

'[He]’s got a beautiful singing voice," he said in a new interview with Total Film. "The person it reminded me of was Bing Crosby. There’s quite a range because it does go from a couple of bigger, showstopper-y sort of things, to moments of real, pure emotion, and he can do it all… I’m going to sound like a crazed fan."

However, King made it clear that 'Wonka' is not a musical. "The Oompa Loompas sing a lot in the book, and Dahl always uses poetry," he said. "But I didn’t want it to just become a musical where people are singing dialogue to each other for no discernible reason. I felt like it was more like a movie with songs than a musical."

King had previously praised his star's singing and dancing abilities, revealing that he did not need to audition for the role as the director had been videos of Chalamet singing in high school.

'Wonka' is released on December 15th.
