Oscar-winner Olivia Colman debuted a blonde hairdo at the Wonka world premiere in London.

Colman, who plays Mrs Scrubbit in the movie, took selfies with fans at the Royal Festival Hall, Southbank Centre and sported a long black dress with a sheer cape for the event.

In a photocall promoting the film the day before the premiere, Colman was pictured in a green dress and was still brunette. It's not the first time she has sported lighter locks, having arrived on the Oscars red carpet in 2020 sporting a blonde crop.

The new adaptation of Roald Dahl's classic tale sees Timothee Chalamet star as Willy Wonka.

The Call Me By Your Name actor, 27, was bare chested when he took to the carpet at the London premiere in a velvet-look suit that was paired with a short-length necklace.

The film is based on Dahl’s Charlie And The Chocolate Factory which was published in 1964, and tells the tale of a chocolate factory full of mind-bending treats and orange Oompa-Loompas.

Chalamet called Wonka a "Christmas film" and said it is "joyful" and "fantastical".

Speaking on the red carpet at the movie's world premiere, he told the PA news agency: "I do think this is a Christmas movie because I think it’s joyful.

"It’s hopeful. It’s fantastical. It’s huge.

"David Heyman is a producer on this, obviously he didn’t direct it, but the films he does, like Harry Potter or Barbie, are these huge world-building movies and this is one of them."

Meanwhile, director and co-writer Paul King spoke about Chalamet’s Willy Wonka in the upcoming movie. He said: "I just think he’s (Chalamet) wonderful.

"This is sort of Willy Wonka 25 years before the events of the chocolate factory. So he’s a very different character.

"It wasn’t like he (Chalamet) was having to channel any of the other performances or do an impression of anyone. It’s very much his own thing.

"But I think what’s so wonderful about him is he captures the warmth of Willy Wonka and the wonder of Willy Wonka.

"Because Willy Wonka is - he’s obviously got quite a brittle, a noble exterior - but at the heart of him, he is an incredibly generous soul who wants to give away his life’s work in the chocolate factory.

"He has that heart of generosity to him and it was lovely to see that character as a younger person taking his first steps out into the world."

The role of Wonka has previously been played by Gene Wilder in 1971, and Johnny Depp in 2005.

Wonka will be released in cinemas on December 8.
