Cillian Murphy’s son goes viral for kooking exactly like the Oscar winner
The moment arrives as Aran begins building a promising acting career of his own
The internet has discovered what many fans are calling the closest thing to a real-life copy-and-paste in Hollywood.
Aran Murphy, the 19-year-old son of Academy Award winner Cillian Murphy , is generating massive attention online after a recent red carpet interview went viral, with viewers stunned by just how much he resembles his famous father.
Within hours of being shared across social media platforms, clips of Aran speaking with presenter Jodie McCallum at the premiere of HBO's upcoming comedy-drama Youth accumulated millions of views. While many viewers were interested in hearing about the young actor's rising career, the conversation quickly shifted to something else entirely: the uncanny similarities between Aran and the Oppenheimer star.
For countless viewers, it was more than just a family resemblance. Social media users pointed out that Aran appears to share not only Cillian Murphy's striking facial features, but also his mannerisms, speech patterns, expressions, body language and even the quiet, thoughtful way he answers questions.
The young actor appears in two high-profile HBO projects
The comparisons spread across X, TikTok, Instagram and Reddit, with many users joking that they were watching a younger version of the Oscar-winning actor. Some fans remarked that Aran looked like Cillian Murphy had somehow stepped into a time machine, while others noted that his voice and delivery were so similar that they had to double-check who was being interviewed.
The viral moment arrives as Aran begins building a promising acting career of his own. While comparisons to his father may be unavoidable, Aran Murphy is quickly establishing himself as a talent worth watching.
The young actor currently appears in two high-profile HBO projects .
One of them is Youth , a new romantic comedy created by and starring Sharon Horgan, the acclaimed writer and actress behind Bad Sisters and Catastrophe. The series follows a 50-year-old divorcee navigating relationships, family responsibilities and life changes while raising her adult son, played by Aran Murphy.
The role has already introduced him to a wider audience and helped spark the viral attention surrounding his red carpet appearance.
Aran is also part of War, an HBO legal drama featuring a star-studded cast that includes Dominic West and Sienna Miller.
Of course, any discussion of Aran Murphy inevitably circles back to his father. Cillian Murphy has spent more than two decades building one of the most respected careers in modern film and television. From 28 Days Later and Inception to his iconic role as Tommy Shelby in Peaky Blinders, Murphy became known for his intense performances and unmistakable screen presence.
That reputation reached another level when he won the Academy Award for Best Actor for his portrayal of J. Robert Oppenheimer. Given that legacy, public interest in Aran was always likely. What few people expected was how strongly audiences would react to seeing the similarities between father and son in motion.
Aran's future appears bright beyond his HBO work. He is also part of the ensemble cast for Klara and the Sun , filmmaker Taika Waititi's adaptation of Kazuo Ishiguro's acclaimed science-fiction novel. The film boasts an impressive lineup that includes Amy Adams, Jenna Ortega, Natasha Lyonne and Steve Buscemi, offering another major platform for the young actor to showcase his abilities.
