Back in 2020, host Richard Osman had viewers gripped with his captivating crime novel series, The Thursday Murder Club.

Jump ahead five years and the debut book is now being adapted into a full-length movie, featuring stars likePierce Brosnan, Ben Kingsley, Celia Imrie and Helen Mirren, who broke down in tears during filming.

The movie centres on a group of residents at a retirement home in a peaceful village who tackle unsolved murder mysteries as a hobby.

But things get complicated when they become entangled in an actual case.

With production beginning last year, fans won't have much longer to wait as the film arrives in UK cinemas on August 22 before becoming available on Netflix from August 28, reports the Express.

Before its debut, Good Morning Britain's showbiz correspondent Richard Arnold revealed some exclusive behind-the-scenes details after chatting with the cast on location last year.

During his conversation with director Chris Columbus, who also helmed the first two Harry Potter movies, he couldn't stop raving about the stellar cast.

Richard commented: "Extraordinary cast you've gathered for this!"

Chris replied: "The best cast I've had since Harry Potter. This is the first time since Potter that every cast member, my first choice has said yes. That never happens to a director."

In a clip featuring Helen Mirren, she revealed to the ITV presenter that each performer has admired the others' work throughout the years.

She added: "I was in the Royal Shakespeare company with Ben, we were both in our early 20s, young actors starting out and of an equal level, ambitious, serious and dedicated.

"You know, very, very straight-laced about the whole thing. Not so much now, up our own [bleep] I would say!"

Despite each leading performer in the movie being a well-established figure in the business, with Pierce being recognised for his portrayal of James Bond in the mid-1990s, it appears they were all starstruck by Richard Osman.

The writer and comedian disclosed that they all wanted him to autograph their copy of his book, as he was delighted they each possessed his novel.

But the penny dropped for Richard as he added: "Of course they've got the book, they're in the film. They're reading it, you idiot!"

The Thursday Murder Club will debut in UK cinemas on August 22. It will then be accessible for streaming on Netflix from August 28.
