Cillian Murphy's son, Aran Murphy, has joined the cast of the upcoming HBO/Merman series YOUTH.

It was previously reported that the 18-year-old was set to make his big screen debut in Taika Waititi's upcoming adaptation, Klara and the Sun, which he'll star in alongside Jenna Ortega and Amy Adams.

It has now been announced that Murphy will star opposite Sharon Horgan in the upcoming series YOUTH.

His agency, Lisa Richards Agency, shared the news on Monday.

“We are pleased to announce that Aran Murphy has joined the cast of the upcoming HBO/ Merman series YOUTH,” they wrote.

“Aran is cast alongside Sharon Horgan, Rupert Friend, Sharlene Whyte and Robbie Gee.

Aran Murphy, son of Cillian Murphy, will hit the big screen with the movie adaptation of Klara and The Sun.

“The series follows a 50-year-old divorcee’s search for sex and love whilst juggling caring for her ailing parents and parenting her should-be grown-up son.” 

Horgan also writes and executive produces the series, alongside additional executive producers Faye Dorn, Jim Kleverweis, and Dawn Shadforth, who will also direct.

Proud dad Cillian Murphy recently told the Irish Examiner: “He’s just a massive fan of film and television and theatre. It’s not really a surprise that he would find his way into it. I’m just happy to support him and let him off, find his own way in it.”
