Cillian Murphy will "definitely" return for the 'Peaky Blinders' movie.

The BBC drama's creator Steven Knight has confirmed that the 'Oppenheimer' star will reprise his role as gangster Tommy Shelby in the big-screen adaptation of the drama that will be filmed later this year.

Speaking to Birmingham World at the premiere of his new BBC series 'This Town', Knight said: "He definitely is returning for it. We're shooting it in September just down the road in Digbeth."

The Oscar-winner's return as Tommy Shelby is unsurprising as he has often talked about his interest in playing the character in a film as long as the script was of sufficient quality.

Cillian told Rolling Stone UK last year: "If there's more story there, I'd love to do it.

"But it has to be right. Steve Knight wrote 36 hours of television, and we left on such a high. I'm really proud of that last series. So, it would have to feel legitimate and justified to do more."

The 47-year-old actor added to the Irish Star last month: "I have always said that if Knight delivers a script that I know he can deliver, because he is such a phenomenal writer, I'll be there.... If we want to watch 50-year-old Tommy Shelby, I will be there. Let's do it."

'Peaky Blinders' aired to critical acclaim on the BBC between 2013 and 2022 and Knight has always been clear about his plans to adapt the Birmingham-set series for the cinema.

He told Esquire: "The film, I know exactly what it's about. And I know what two stories it's going to tell.

"What will happen after that, I want that to depend on the film. For all we know somebody is going to pop out – I think I know who it's going to be."
