Aran Murphy, the 17-year-old son of actor Cillian Murphy and artist Yvonne McGuinness, is stepping into the spotlight with a significant new role. He has been cast in the upcoming HBO and Sky series War, which was announced by his talent agency on October 22. This marks an important milestone in Aran’s acting career as he joins a cast that includes Dominic West and Sienna Miller.
Aran Murphy’s Breakthrough Role in the Legal Thriller “War”
The series War centers on a complicated divorce between a powerful tech magnate, portrayed by Dominic West, and an international star played by Sienna Miller. The story unfolds as two competing law firms battle for dominance both inside and outside the courtroom. Set in London, this drama explores themes of conflict, power, and personal turmoil.
For Aran Murphy, this HBO and Sky project will be his first television appearance. However, he is no stranger to acting, having appeared in the 2022 Irish film Lola. In addition, he recently completed filming on Taika Waititi’s adaptation of Klara and the Sun, where he stars alongside notable actors Amy Adams, Jenna Ortega, and Steve Buscemi. His evolving career suggests a promising future in the industry.
Cillian Murphy’s Reflections on His Son’s Growing Career
Cillian Murphy, renowned for his role in Oppenheimer, generally maintains a private stance regarding his family life. Still, he has spoken openly about his pride in Aran’s acting talents on a few occasions. In March 2024, during an interview with Ireland’s Today FM, Murphy expressed heartfelt admiration for his son’s craft.

“I’m very, very proud of him,”
Cillian Murphy said.
“He’s a great, great actor, so I’m very proud of him.”
Despite his encouragement, Cillian is careful to respect Aran’s independence in his career choices. He emphasized that his son does not require unsolicited guidance.
“He doesn’t need my advice,”
Cillian explained.
“He’s well able.”
Besides Aran, Cillian and Yvonne McGuinness have another son, Malachy, who is 19. The actor’s commitment to his family was also evident at the Palm Springs International Film Awards in January 2024, where Cillian accepted a trophy for his performance in Oppenheimer. In his acceptance speech, he conveyed deep gratitude to his wife and sons for their support during demanding projects.
“Because I don’t ever really get to do this too often, I want to say thanks to my family,”
Murphy said, per People.
“Two-thirds of them are sitting down there. We had to leave one of them at home doing exams. But just thanks for putting up with me—putting up with the half me and the shadow me and the absent me, the remains of me when I’m doing a film like this or work in general.”
“You’re always there. I love it. So thanks, guys.”

The increasing visibility of children like Aran Murphy entering the entertainment industry underscores both the opportunities and pressures that come with public expectations. As Aran takes on a major project with HBO and Sky, his journey will be closely watched by fans and industry observers alike, particularly given his lineage and the accomplishments of his parents.

This balance of legacy and individual talent will be critical as Aran continues to develop his presence in film and television.
As audiences await the release of the series War and watch Aran Murphy’s progress alongside respected actors such as Dominic West and Sienna Miller, his evolving path exemplifies ongoing generational shifts within the entertainment world.
