On the red carpet of the HBO series premiere of "Youth," 19-year-old Arán Murphy, the youngest son of "Oppenheimer" star Cillian Murphy, chatted with journalists. Video clips of his interview quickly went viral on social media, racking up millions of views within a day. Audiences were drawn not only to his acting work in the project, but also to the way he carries himself on camera. ### Viral Interview at the Premiere Users noted the striking resemblance between Arán and his father — from his facial features, gaze, and expressions to his manner of speaking and his behavior on camera. On social media, fans joke that the young man looks like a "younger version" of Cillian Murphy, and some pointed out that even without knowing who was giving the interview, one could immediately guess the family tie to the "Oppenheimer" star. Users were especially amused by his restrained, almost emotionless delivery of answers to questions about his role in the series, which many found reminiscent of his father's signature style. ### Two HBO Series and a Major Film Debut The 19-year-old actor is currently filming two HBO projects at the same time. In the series "Youth," he plays the son of Sharon Horgan's character — a 50-year-old divorced woman trying to get her personal life back on track while caring for her parents and raising an adult son. In the legal drama "War," he will appear alongside Dominic West and Sienna Miller: the plot centers on the rivalry between two London law firms, with Arán portraying the son of the characters played by West and Miller. ### Feature Film Debut Beyond his television projects, the young man is set to make his feature film debut. He starred in "Klara and the Sun" — an adaptation of the eponymous novel by Nobel laureate Kazuo Ishiguro, directed by Taika Waititi. The lead roles in the film were played by Jenna Ortega, Amy Adams, and Mia Tharia. ### Family and Background Arán Murphy is the youngest son of Cillian Murphy and Irish artist Yvonne McGuinness. The couple also has an older son, Malachy, born in 2005. Thus, the actor's son, not yet twenty, has already made his mark in two HBO series and a major film project, and his public appearance at the premiere once again drew attention to the Murphy family dynasty. ## 🔍 Fact-Check Verification - ["A Copy of Dad."
