Keegan-Michael Key, who stars in the upcoming 'Wonka' has told The Hollywood Reporter that the musical is "wondrous and a little bit epic."

"[Timothée Chalamet] has seven musical numbers and I have two, one of them is a group number and another is a smaller group number," explained Key.

In a recent interview with British Vogue, Chalamet, who plays the titular chocolatier, described the film as "so sincere" and "so joyous."

Key, whose role in the film is yet to be announced, added to Chalamet's sentiments. "I would agree with all the adjectives Timothée used and I would also like to add the words wondrous and a little bit epic.

"It's a nice, big, full, beautiful piece of art and Paul King, who directed it, is a delightful human being who has this wonderful, childlike heart. He was the perfect person to direct the project."

On the subject of Chalamet, Key went on to heap praise on the lead actor. "There’s this wonderful effortlessness about how he plays Wonka, not to mention the fact that there’s this hopeful quality that he gives the character, a kind of indomitable quality that he’ll never quit, he’s always up for the next thing.

"He’s like, ‘OK, that didn’t work out? We’ll do this and we’ll try something else,’" said Key, who co-stars alongside Olivia Colman, Sally Hawkins, Matt Lucas, Rowan Atkinson, Natasha Rothwell, Rufus Jones, Simon Farnaby and others.

"And Timothée Chalamet, what can I say? Sacrébleu! This kid, you know, he drips charisma and a wonderful confidence. He’s just a really delicious artist."

Last October, Chalamet shared a first-look image of himself in the lead role of the upcoming movie from 'Paddington' and 'Paddington 2' director King.

'Wonka' is set for release Dec. 15, 2023.
