Leighton Meester, Adam Brody Share Whether Kids Will Follow in Their Footsteps
Cillian Murphy’s son has some explosive news.
Aran Murphy, the 17-year-old son of the Oppenheimer actor and his wife Yvonne McGuinness, is set to star in the upcoming HBO and Sky series War alongside Dominic West and Sienna Miller, according to an Oct. 22 Instagram announcement from his talent agency.
The legal thriller will see a high-powered tech titan (Dominic) and an international superstar (Sienna) go through a messy divorce as two rival law firms compete to triumph both in the courtroom and the world outside of it, per TV Insider.
While the London-based series will be the teen’s first TV show, he previously starred in the 2022 Irish film Lola and has completed filming Taika Waititi’s movie adaptation of Klara and the Sun, which he stars in alongside Amy Adams, Jenna Ortega and Steve Buscemi, per IMDb.
Though Cillian—who also shares son Malachy, 19, with Yvonne—typically keeps his family life private, he previously detailed how he feels about Aran following in his acting footsteps.
“I’m very, very proud of him,” he told Ireland’s Today FM in March 2024. “He’s a great, great actor, so I’m very proud of him.”
But while the Dark Knight actor is excited for his son’s career, he isn’t offering Aran any unsolicited pointers.

“He doesn’t need my advice,” the 49-year-old continued. “He’s well able.”
Meanwhile, Cillian took an opportunity to detail the immense gratitude he has for both of his sons and wife while accepting a trophy at the Palm Springs International Film Awards in January 2024 for his performance in Oppenheimer.
“Because I don't ever really get to do this too often, I want to say thanks to my family," he said at the event, 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."
He added, "You're always there. I love it. So thanks, guys."
