“You’re an Irishman, are ya?” Cillian Murphy says, his features visibly softening, as I begin talking over Zoom. “Thank god.”
Two truisms about Cillian Murphy that are often repeated online: He hates doing interviews, but he loves Ireland. If he must talk to the press – which, being the lead of Christopher Nolan's mammoth blockbuster Oppenheimer, he absolutely must – the least I can do is give him a chance to talk about our shared homeland. So, with this introduction, we're off to a good start.
It's about 10 days before Oppenheimer drops, but Murphy and the big A-bomb movie – along with Greta Gerwig's Barbie – already seem to be taking up the majority of the internet's consciousness. In the film, he plays J Robert Oppenheimer, the man credited with leading the creation of the atomic bomb during World War Two. Though he has starred in a handful of Christopher Nolan blockbusters already, this is his first as a proper leading man. So, the scrutiny is greater than ever. He is wearing it well. “I'm not a huge fan of talking about myself,” he says, “but I fully believe in this movie, and I love promoting it. So I'm very comfortable with all of that.”
GQ: How often do you get people calling you “Sillian”?
Cillian Murphy: Less and less now actually. But it doesn't bother me. Then I very pedantically explain to them that there's no ‘K’ in the Irish language and it gets really boring.
You used to live in London, but moved to Dublin in 2015. I heard you said your kids were getting English accents so you took them home.
Yeah. That was a joke. [Laughs].
Well, people have really run with it. Do you need to personally relate to characters, and could you do so with Oppenheimer?
Well, first of all, it's imperative not to judge the character. Because then you've lost as a performer. You have to try and understand [them]. You have to be like a kind of emotional detective. But your job primarily is to define the truth in the character to try and portray them in a truthful way.
Emily Blunt said recently that during filming you didn't go for cast dinners because your ‘brain was too full’. Robert Downey Jr. said that at times it felt like you were ‘icing’ him. How much did playing Oppenheimer affect you?
It was a big part, and there were big, big questions that were grappling with, these huge ethical, moral questions. And Chris had written the script in the first person. So I knew that a lot of the weight was on my shoulders, even though we have this incredible ensemble. There was a responsibility that I felt about playing the part. That's just the way I work. I get very consumed by the work, and I don't really have time for hanging out. And in this movie, I was [regularly] skipping dinner, you know, so I wasn't great craic to hang out with. But that's just the way it was. It's just the nature of the work.
You’re not method, though, right?
Well, here's the thing, right? Method is like a euphemism. We all have a method to get to the final result. And whatever that method is, it's personal and unique to each actor. It's become sort of confused, I think, with the Stanislavski approach. But every actor has their own individual method.
Yeah. But you’re not what people generally view to be method, staying in character the whole time?
Inevitably, if you play a character for a long time, and I was researching him for six months, then shooting it for however long that was.. And you're playing them 18 hours a day every day. By osmosis, you're exchanging atoms, You become consumed or immersed [by it], that's just the way it is.
You mentioned skipping meals. What was the weirdest food day that you had while you were losing all that weight?
Oh, man. I just want to be very careful on this. This was for work, and we structured it pretty well. Inevitably, you do start getting competitive with yourself and all that, but it was for a purpose. He was a very, very slight guy. And he was very self-conscious about that. And it gave him this very unique, particular kind of iconic silhouette. And when you're that weight, it affects the way clothes hang on you, it affects the way you walk, it obviously changes the shape of your face and all that. So that was very useful for the character. But I really don't want to make a big deal about ‘oh, Cillian lost all this weight’.
Taking this lead role on has brought a lot of attention. I've read recent interviews you've done that it's not necessarily your favourite thing. Do you at times feel like the pressure of being the leading man, especially in a movie on this scale is a lot to deal with?
Yeah, but to clarify the thing about interviews, I love talking about the movie, I love talking about music and books and art. I'm not a huge fan of talking about myself. And I don't, and I don't think anyone really is, but I fully believe in this movie, and I love promoting it. So I'm very comfortable with all of that. And in terms of, you know, how it changes your life or anything like that, or changes how people perceive you that that hasn't changed for me, you know, my life has been exactly the same as it always was.
The Oppenheimer script is very dense. How much does that impact how you go about shooting it?
You have to be completely prepared. I knew the script more or less before we went into work, which isn't so not something I've ever done before. Only in theatre, because there was so much text, and it was quite dense. I wanted to not be worried about the text when I went on the floor. But then, a lot of the scenes I have with Downey, it was quite loose and quite improvisational. I mean, acting with him was was was was just extraordinary. He's just electrifying, the most available engaged, present, unpredictably brilliant actor I've ever worked with.
The film ends on a close-up shot of you, taking in the weight of what the preceding 3 hours have meant for the future of mankind. What are you thinking in that moment when you’re shooting it, knowing you’ve got the weight of the movie on your shoulders?
You can't let it get into your head. You've just got to think about the truth of the scene. For example, when we were shooting the Trinity test, all of us actors and Chris and all the crew, were aware of the weight of that sequence, and what it meant, but you can't let it control you, you know. And I think I've learned that over the years, you know, when you get on the floor, and you get on, you just forget about that stuff. You have to train your mind to not let it affect your performance.
Were you there for the actual explosion that was created?
I was there for components of it. There are different sort of sections of it. I was there for some of it. With Chris, everything is done for real. I've never done a green screen scene with Chris and I never will, I imagine. So what it does is it puts the performer into the atmosphere, or the environment as close as possible to what the character is feeling. You know, and I've, I've been out in boats with Chris on the sea and up in mountains in the snow. It just elevates your performance.
There has been a lot of chatter about the sex scene in this movie, and a wider chat about whether sex scenes are necessary in film at all. Where do you fall on that?
I think they were vital in this in this movie. I think the relationship that he has with Jean Tatlock is one of the most crucial emotional parts of the film. I think if they're key to the story then they're worthwhile. Listen, no one likes doing them, they're the most awkward possible part of our job. But sometimes you have to get on with it.
With a bit of distance between yourself and Oppenheimer, are you able to judge him just a little bit?
I'm really not going to give you an opinion on that. I really strongly believe that the film should ask the questions of the audience. And I don't want to prejudice anybody's point of view, when they go into the movie theatre, about what how they feel and Oppenheimer. What I will say, is that Oppenheimer – Chris called him the most important man that ever lived, whatever you think about that. That's up to you. But we are living in a world that was changed by Oppenheimer. We're living in a nuclear age because of what Oppenheimer did.
You and Christopher Nolan have discussed how you nearly got the role of Batman. Is there a part of you that thinks that it was maybe for the best that you didn’t?
Yes, I think it was for the best because we got Christian Bale's performance, which is a stunning interpretation of that role. I never considered myself as the right physical specimen for Batman. To me, it was always going to be Christian Bale.
Tom Hardy didn’t make it into this Nolan film. Do you have plans to work together again?
He's one of the best actors in the business. And we've developed this great trust and shorthand and there's a nice kind of chemistry, I think, between the two of us. I'd love to work with him again. Maybe there'll be a Peaky Blinders film. Maybe we'll get to do it there. I'm not sure.
What’s the latest on the Peaky Blinders film?
I have no update for you, man. I'm waiting to hear, but it's a tricky time with all these strikes and everything going on. I’ve always said that if there's more story to tell, I'd be there.
