After a four-year absence, Peaky Blinders is back — and this time, Tommy Shelby has made it to the big screen.

The Birmingham-set drama has been given the cinematic treatment with The Immortal Man, which debuted in cinemas earlier this month before its arrival on Netflix tomorrow (20 March). Starring Cillian Murphy as the aforementioned Tommy, we return to the second city just as the Second World War is beginning to take hold, with the anti-hero facing ‘his most destructive reckoning yet’.

To mark the release of the film, M sat down with longtime Peaky Blinders composers Antony Genn and Martin Slattery to talk about the process of scoring The Immortal Man — you can watch our interview with Antony and Martin below.

In our interview, Antony and Martin tell us about how deeply involved Cillian was in the music side of the production of The Immortal Man.

'Cillian Murphy is a very, very musical person — he's a musician himself,' Antony explains. 'He happens to be a very successful actor, but he's also a musician, so his understanding of music is coming from a fundamental place. He's also an absolute fan of music — I'd say he's more than a fan, he's an obsessive. As am I!'

The pair also tell us about the collaborators they worked with on The Immortal Man soundtrack, including Fontaines D.C. frontman Grian Chatten on such tracks as Puppet and Black Dahlia.

‘Grian is a great poet,’ Antony says. ‘His voice sounds like it’s 50,000ft tall and made out of fucking granite. He’s a force, man.’

Grian is joined on the soundtrack by his Fontaines bandmates Carlos O’Connell and Tom Coll, while the likes of Nick Cave, Girl In The Year Above, Amyl and The Sniffers’ Amy Taylor, Lankum and McLusky also feature.

‘As composers with an idea, I don’t think we could’ve got a better group of people [to work with] if we’d sat and thought about it for a year,’ Martin says.

Peaky Blinders has become a global phenomenon for sure,' Antony adds later in our chat. 'We’re very lucky and grateful to be a part of it.'

Peaky Blinders: The Immortal Man is out on Netflix on 20 March.
