Aaran Murphy, 19, made his red‑carpet debut at the London premiere of HBO’s new comedy Youth, instantly sparking social‑media buzz for his uncanny resemblance to father Cillian Murphy.

The young actor arrived in a classic suit, and fans quickly noted that his voice, facial features and even his posture mirrored his dad’s. One commentator wrote, “His voice, face, expression—everything like his dad. Cillian Murphy seemed to press copy and paste.” Another joked, “The apple didn’t even fall.”

At the event he was introduced as a guest, but he also appears in the series as the son of Sharon Horgan’s character, a 50‑year‑old divorced woman, adding a layer of on‑screen family drama to the comedy.

Cillian Murphy has been married to Ivonne McGuinness since 2004, and the couple’s two sons are Aaran, 19, and Malaki, 20. In a 2023 Rolling Stone UK interview, the veteran actor said his children think all his movies are “very intense.”

Aaran’s résumé already includes a role in a dramatic series about divorce that co‑stars Siobhan Miller and Dominic West, with the show slated to premiere in October.

With the positive response to his London appearance, observers expect the young star to take on more screen work in the coming months.
