A familiar face on the carpet

Cillian Murphy's 19-year-old son Aran has landed a role in a major new HBO series, and photos of him instantly drew comparisons to his father.

The show is called Youth

Aran joins the cast of Youth, a new HBO drama that has been building anticipation ahead of release.

He plays Ruairi

Aran's character is a teenage son who is emotionally unravelling and gets pulled into dangerous social media trends.

Serious co-stars

He acts alongside Sharon Horgan, Rupert Friend and Robbie Gee, a cast with real weight behind it.

London screening on Friday

Aran walked the red carpet in London with his co-stars, including Sharon Horgan and Sharlene Whyte, for a screening of the show.

The photos went viral

Pictures from the screening spread fast online, with people stopping on the resemblance rather than the show itself.

Copy and paste

Commenters piled in with the same reaction over and over, insisting the two men were indistinguishable.

“Literally copy and paste Cillian to a T!!!”

No DNA test needed

Other reactions ranged from disbelief to jokes about cloning, all landing on the same point about the family likeness.

“Oh my God, they cloned him!”

Already a real resume

Aran is young, but he has built a portfolio across both film and television rather than arriving out of nowhere.

Klara and the Sun

Earlier this year he appeared in Taika Waititi's science fiction adaptation alongside Jenna Ortega and Amy Adams.

A second HBO credit

Last year he joined WAR, an HBO and Sky co-production featuring Dominic West and Sienna Miller.

Debut in Lola

His first feature was Andrew Legge's indie science fiction mystery Lola in 2022, which drew strong reviews.

The Taylor Swift story

Cillian took his family to an Oscars party, where his sons ended up in conversation with Taylor Swift.

“I don't think my kids were legally allowed to be there.”

She remembered them

On The Graham Norton Show, Swift praised the boys for being both interesting and interested, which she called a real accomplishment.

“Your sons are the future of our world.”

Spotted in the audience

Cillian was not sure Aran was even in the studio. Swift picked him out of the crowd on sight and pointed him out.

“Oh he's right there, you can tell!”

Graham Norton's verdict

The host joked that the family resemblance was so obvious it would have been a guaranteed win in a guessing game.

“If this was a game show we've all just won a prize.”

Home is Dublin now

Cillian reportedly paid close to 1.7 million pounds for a Victorian townhouse in south Co. Dublin, built in 1863, with six double bedrooms.

Fourteen years in London

Both sons were born in London and stayed until 2015, when the family moved back to Ireland.

“It's kind of an Irish story, you know, to move away, do your thing and then come home.”

Those posh accents

Cillian joked that part of the reason for the move was that his preteen sons were sounding very English, and he wanted them to be Irish.

“they had very posh English accents and I wasn't appreciating that too much”

The other brother

Malachy, 20, has gone toward music instead of acting, a passion his father has encouraged.
