Cillian Murphy loathes interviews and looks visibly tortured at points during our interview. We are sitting in an empty upstairs room of a restaurant near his house in Monkstown, Co Dublin. The room is dark, the sun shining through a solitary Velux lighting his features like a Géricault. But he relaxes when I ask if he’s pleased with Oppenheimer, the latest Christopher Nolan epic.
“I am, yeah,” he says. “I don’t like watching myself – it’s like, ‘Oh, f**king hell’ – but it’s an extraordinary piece of work. Very provocative and powerful. It feels sometimes like a biopic, sometimes like a thriller, sometimes like a horror. It’s going to knock people out,” he adds. “What [Nolan] does with film, it f**ks you up a little bit.”
Nolan wouldn’t disagree. The director recently told Wired magazine that some of those who’d seen it were left “absolutely devastated … they can’t speak”. Which sounds like a bad thing, but is related perhaps to the thought of the 214,000 Japanese people, overwhelmingly civilians, who lost their lives when the bombs were dropped.
Kai Bird, the historian who co-authored American Prometheus, the 2008 biography of J Robert Oppenheimer upon, which the film is based, said he was still “emotionally recovering” from seeing the film, clarifying that it was “a stunning artistic achievement”.

How your mini travel shampoo is costing your pocket and the planet - here’s an alternative
Murphy’s portrayal is said to be astonishing (“Oscar-worthy” is the buzz). (This interview takes place before union representing Hollywood actors formally announced a strike. The strike by the Screen Actors Guild-American Federation of Television and Radio Artists (Sag-Aftra) marks the first time in 63 years Hollywood writers and actors are striking simultaneously. Cillian Murphy, Emily Blunt and Matt Damon were among the stars who staged a walk-out from the premiere to “write their picket signs” ahead of the Sag-Aftra strike announcement.)
While Hollywood might not know him as a leading man, this quietly intense actor has long been celebrated in Ireland and the UK, most notably for his nine-year stint as Tommy Shelby in Peaky Blinders. When he first appeared on our screens, looking like a renaissance painting of St Sebastian – chiselled head contrasting with translucent blue eyes – it was impossible not to be distracted.
Murphy appeared first on stage in Enda Walsh’s Disco Pigs, then the screen adaptation. Then 28 Days Later; Intermission; Ken Loach’s The Wind That Shakes the Barley. Previous collaborations with Nolan include the Dark Knight trilogy, Inception and Dunkirk, “significant milestones in my career,” he says, adding that Nolan “might be the perfect director”.
It was Nolan’s wife, the producer Emma Thomas, who called Murphy one afternoon at the home he shares with his wife, artist Yvonne McGuinness, and two teenage sons. Nolan doesn’t actually have a telephone, or an email, or computer for that matter: “He’s the most analogue individual you could possibly encounter.”
So, Emma said Chris would like a word and passed the receiver, then the director came on the line. “Cillian, I’d love you to play the lead in this new thing,” Nolan said. Murphy tries to recreate his response to this news. “I was lost for words. But thrilled. Like beyond thrilled.” It is characteristic of Murphy that the modulation of his voice barely changes as he expresses this. He was so stunned, he had to sit down. “Your mind explodes.”
The three-minute trailer of the three-hour feature is a rush of snapshots against the crackling of a Geiger counter. There’s Murphy, short back and sides, lifting 1940s eye goggles; blue and red atoms coming at him fast; orange light; white light; blackout; silence. A massive explosion against the backdrop of space. Overlaid is Murphy’s narration: “We’re in a race against the Nazis / and I know what it means / if the Nazis have a bomb.” There’s Matt Damon looking porky as army general Leslie Groves, director of the Manhattan Project: “They have a 12-month head start.” Murphy, pointing with cigarette: “18.”
He has put back on some of the weight he lost for the part, I’m relieved to see; his skin isn’t quite so taut over his skull and there are freckles over those eagle-wing cheekbones. He was determined to nail the scientist’s silhouette “with the porkpie hat and the pipe”, testing himself to see how little he could eat. “You become competitive with yourself a little bit which is not healthy. I don’t advise it.” He won’t say how many kilograms he lost, or what food the nutritionist told him to cut out. NDA? “Ach, no. I don’t want it to be, ‘Cillian lost x weight for the part’.”
Then again, the hurtling speed at which Nolan worked, criss-crossing the US, made it easy to skip meals. Murphy began to forget about food in the same way he began to forget about sleep. “It’s like you’re on this f**king train that’s just bombing. It’s bang, bang, bang, bang. You sleep for a few hours, get up, bang it again. I was running on crazy energy; I went over a threshold to where I was not worrying about food or anything. I was so in it, a state of hyper …” he gropes for the word, “hyper something. But it was good because the character was like that. He never ate.”
Oppenheimer subsisted on little more than Chesterfield cigarettes and double-strength martinis, rims dipped in lime. “Cigarettes and pipes. He would alternate between the two. That’s what did [it] for him in the end,” Murphy adds, a nod to the scientist’s death from cancer in 1967. “I’ve smoked so many fake cigarettes for Peaky and this. My next character will not be a smoker. They can’t be good for you. Even herbal cigarettes have health warnings now.”

I raise method acting and Murphy tilts his head and frowns. “Method acting is a sort of … No,” he says, firm but with a half smile. Oppenheimer had many defining characteristics, not least walking on the balls of his feet and a vocal tic that sounded like nim-nim-nim, but Murphy didn’t want to do an impression. Nolan was obsessed with the brillo-texture hair, so they spent “a long time working on hair”. And the voice. The real question for Murphy was what combination – ambition, madness, delusion, deep hatred of the Nazi regime? – allowed this theoretical physicist to agree to an experiment he knew could obliterate humankind. “He was dancing between the raindrops morally. He was complex, contradictory, polymathic; incredibly attractive intellectually and charismatic, but,” he decides, “ultimately unknowable.”
“Listen, it’s not like a spoiler,” Murphy says, checking himself before he leans in, “but there are incidents in his early life that were quite worrying; very erratic.” They are in the film and the book, he steers. I suspect he is referring to Oppenheimer’s postgrad at Cambridge in 1926, when he placed a poisoned apple on the desk of a tutor towards whom he harboured complicated feelings of inadequacy and jealousy. Arguably, this was attempted murder. But Oppenheimer’s rich New York parents rushed in to bundle him into psychoanalysis. He was diagnosed with “dementia praecox”, a term describing symptoms associated with schizophrenia.
Murphy likes these complex characters; they’re his meat. People that don’t necessarily follow the – yawn – traditional transformative arc of storytelling. Not villains, exactly (although he’s played a few, including Scarecrow in Dark Knight and Jackson Rippner in Red Eye): “Villains are good if they’re well written, but if it’s one note or a trope, then they are dull.” He likes a script to stretch leisurely into all corners of the human condition, “all the shades”. At the same time, you have to understand his exceptional ability to portray interiority, physically manifesting intense human emotion without a word, radiating fierce, consuming energy. Which he does today, actually, when I stray off track.
Although Nolan is usually, shall we say, antiseptic in his approach to romance, Oppenheimer represents a significant shift. He told Wired the love story aspect “is as strong as I’ve ever done”. It features nudity for Murphy and Florence Pugh, who plays Oppenheimer’s ex-fiancee, as well as sex, and there are complicated scenes with Emily Blunt, who plays his wife, “that were pretty heavy”.
He asks if I’ve heard of chemistry tests. “They put two actors in a room to see if there’s any spark, and have all the producers and director at a table watching. I don’t know what metric they use, and it seems so outrageously silly, but sometimes you get a chemistry and nobody knows why.” This is a roundabout way of saying his scenes with Blunt and Pugh conjure this magic. His established bond with Blunt (they co-starred in A Quiet Place II) meant “the audience gets something for free”, he says. “You can be immediately vulnerable and open, and try stuff. There were moments where I remember saying, ‘I couldn’t have done that if it wasn’t with you.’”
Murphy (47) grew up the eldest of four in Cork. His father was a civil servant, his mother a French teacher. They were a middle-class family, musical; his father “can pick up any instrument”, his brother played piano, and they regularly got stuck into “traditional Irish sessions”. Bookshelves were stuffed with literature, the radio often on, the “shitty” TV set not so much. Home life was busy but his parents taught him French and Irish, and sent him to an all-boys academic, rugby-playing private school. “I got all the education” he says, drily.
The story of how much he disliked the Presentation Brothers College, the hard-drinking masculine emphasis, how he found solace playing guitar in a band, is much rehearsed and he says today he doesn’t want “to slag the school off. I hear it’s great now”. Something about this experience seems nonetheless unsettling. He had one friend, who is still his best friend, “so I wasn’t, like, an outcast”. He played rugby for the first couple of years, but abandoned it “because everyone was all of a sudden towering over me”. Was it an unhappy time? He shifts. “It was okay. I was a bit of a messer, like I’d get in trouble and say nothing. It wasn’t the ideal school for me.”
I don’t enjoy the personality side of being an actor. I don’t understand why it’s expected I’ll be scintillating on a talkshow
Murphy enrolled in and dropped out of a law degree at University College Cork (UCC), which created some friction with his parents (when I ask if his own sons will go to university in Dublin, he says, “whatever they want”). He continued with the band, his first creative love but the one that got away. When they were offered a contract with Acid Jazz records, he turned it down for a number of reasons, he says, crucially that he didn’t feel good enough. Murphy still writes and plays at home but, no, you won’t be hearing any of his recordings, ever, he says.
It’s a funny thing talking to Murphy. He’s at once garrulous (on the craft, or literature, or ideas) and reticent (pretty much anything else). I sense in previous interviews that he skates over issues close to his heart – such as the expression of emotion in Ireland and the need to teach empathy in schools. But when I try to drill in to these topics, get to the root, he clams shut, emitting energy like a nuclear reactor.

Later, in a different context, he will tell me a truth: “I’m stubborn and lacking in confidence, which is a terrible combination. I don’t want to put anything out that I don’t think is excellent.” But he clearly hates the pantomime of publicity, asking why I am returning to certain topics and repeating lines I’ve read elsewhere. I can almost see him at home with its views towards the Irish Sea, complaining to his wife as they tuck into supper: “Another one, asking the same f**king questions.”
If he could get out of going to Cannes, of standing on red carpets, dressed as is his habit for a funeral, hair shellacked, hands in pockets; if he could turn his back on the coloured-foam mics thrust in his face, he would. He really would. No, it dawns on him now, there’s something even worse than the red carpet; there’s the talkshow rounds. The very word “talkshow” comes out of him like a pain from his rib cage, as if the parcelling out of amuse-bouche anecdotes, offering them up to the forced laughter of that false god of show business, the studio audience, is in itself the most cheapening experience known to mankind.
[ Cillian Murphy: ‘The less that people know about me the better’Opens in new window ]
“I do them because you’re contractually obliged to. I just endure them. I’ve always found it difficult. I’ve said this so many, many times.” Then there’s the double wince of realising that, yes, he’s done it again. He’s laid into the industry that feeds him. His hands raise slowly in surrender. “I want to just caveat this by saying, I’m so privileged. I’m so happy to be doing what I love. I’m really lucky. But I don’t enjoy the personality side of being an actor. I don’t understand why I should be entertaining and scintillating on a talkshow. I don’t know why all of a sudden that’s expected of me. Why?”
There’s an awkward silence. I say that he reminds me of Naomi Osaka, the tennis player who refused to talk to journalists after the French Open in 2021. He says he feels “100 per cent” sympathy with her, “because why should she have to perform?” Then he relents. “But I get it. I get it’s a kind of ecosystem where the film feeds the publicity which feeds the talkshows which goes back and feeds the film, so, like, that’s how it works. I suppose I’m just not good at it. At interviews, at this stuff,” he gestures at me. He says after he leaves me today he’ll be going down the stairs thinking of all the things he’s said and worrying it’s come across all wrong. “Do you know what Sam Beckett said? ‘I have no views to inter.’ I love that. That should be the interview.”
We return to his art, the tension falls away and he’s back to his charming self, charged air evaporating. Since Oppenheimer, he’s also wrapped Small Things Like These, an adaptation of Claire Keegan’s brilliant novella set in 1985 in a small Irish town on the edge of which is a convent and “laundry”. Murphy is a huge fan of Keegan. He remembers reading her 2010 novel Foster on a train and having to pull his hoodie over his face because he was crying so hard. Anyway, he’d wanted to work with the Peaky Blinders director Tim Mielants and they were throwing ideas around in his sittingroom when Murphy’s wife suggested Small Things. “No, there’s no way,” Murphy said. “That’s going to be gone already.” But when he called the agent, he found it was available. “I went, ‘No, you’ve got to be f**king kidding.’” Murphy pitched the idea to Matt Damon, who has set up a studio with Ben Affleck. “From there it all just happened really quickly.”
I’m always trying to cut lines in scenes. I like films that pose the big questions, then leave it to the audience
Murphy plays Bill Furlong who, funnily enough, is a man of few words. Keegan’s light-touch writing is everything he loves in art – the sense that you are not being bashed over the head by an idea. That’s how he tries to act, he adds.
“I’m always trying to cut lines in scenes, because I feel like you can transmit it. Like when you see a person on a train thinking, or driving a car, and you are purely observing someone and feeling the energy that is vibrating from them. That’s the sort of acting I love. In a lot of film and television, they want to cut those bits to go to the action. I like films that pose the big questions and then leave it to the audience.” Perhaps this is at the heart of his reticence in interviews? That he doesn’t feel the need to explain.
Murphy still finds it “nuts” that the last of the Magdalene laundries closed in 1996, that it was illegal to buy condoms in Ireland until 1985, that divorce was made legal only in 1996. He remembers vividly thousands of people still going to see moving statues in Cork when he was growing up.
“Crazy. But, like, how far the country has come since then, we’re so socially advanced now compared with where we were. But you must look back. And art is a better way of doing that than reading all these reports [into the laundries].” (Afterwards, he emails me: “The nation is actually dealing with an unresolved collective trauma. Who knows how long this will take to heal, but I feel strongly that art, film and literature can help with that process. It’s a kinder and gentler sort of therapy. I hope that our movie can help with that in its own little way.”)
Because he’s a nice man, because he doesn’t want me to feel bad about our encounter, and because he’s generous and hospitable, Murphy finishes by telling me some of the best places to visit in Ireland. He and his family are staying here for the summer. They’ve had it with air travel and his hometown of Cork is only a couple of hours away. He supplies me with other recommendations: a great book he’s just read, Brian, by Jeremy Cooper, oh, and there’s the Francis Bacon studio exhibition I should catch on my way out.

But before I go, what has he learned from playing Oppenheimer? Foremost, he says, that scientists think differently. He knew this already from playing physicist Robert Capa in Danny Boyle’s Sunshine (2007) and hanging out in Cern, home of the Large Hadron Collider in Geneva, for research.
“I had dinner with all these geniuses. I’ll never understand quantum mechanics, but I was interested in what science does to their perspective.” He sought their opinions on subjects that matter – love, politics, our place in the universe, “infinity, or whatever the f**k. Because they have a completely different way of taking in information than we do. I remember one scientist saying, ‘I don’t believe in love. It’s a biological phenomenon, the exchange of hormones between the female and the male. That’s all. Love is a nonsense.’” Murphy taps the table with his hand. “I couldn’t go along with that, obviously.” – Guardian
