​In the past, Keoghan has been outspoken about his upbringing, which saw him and his brother sent to different foster homes as their mother struggled, and later died, from drug addiction. The brand new Netflix film is a spin-off from the acclaimed TV series, which ended in 2022. It stars Keoghan as the illegitimate son abandoned by the main character Tommy Shelby, played by Cillian Murphy. He said that the “absent” relationship between his character, Erasmus “Duke” Shelby, and his on-screen father reminded him of his relationship with his real father. The 33-year-old said: “It’s a real thing, stepping into play Tommy Shelby’s son. Being a big fan of the show and a big fan of Cillian, I wanted to be part of it and get my teeth into it. “It was the relationship, for me, and it was the absence I leaned into, and the experience I have in some similar ways to my absence of my dad, and the echoes I’ve heard of him and the kind of figure I’ve made him to be. “I felt that was… a humanity. It sort of humanises Duke for me to show those vulnerabilities. “Obviously, the kid’s going to be an absolute livewire and violent and they’re all reactions, they’re all cries for help – not to justify each and every one.” The film follows Tommy (Cillian Murphy) as he is driven back from his self-imposed exile amid the chaos of the Second World War, where he finds Duke leading a violent crime gang, the Peaky Blinders. Keoghan continued: “At the end of the day, there’s an animalistic thing of the cub looking for its dad. “That’s what I brought it back to when (Tommy) is finally there. This behaviour he does when he’s not there, emulating him and trying to be like him from what he’s heard, and trying to put it on to when he is with him. “I wanted to lean into that, make that a conscious thing.” Recommended reading: BBC’s Peaky Blinders returning to TV with two new series Peaky Blinders TV programme open casting call in Birmingham Stars hit red carpet for premiere of Peaky Blinders: The Immortal Man The Bafta-winning actor is a new addition to Peaky Blinders, and said “it was mad” to join a franchise that is “just iconic”.
