Cillian Murphy's son Aran is joining an A-list cast in new movie

Cillian Murphy's son is making his feature film debut.

The Peaky Blinders star shares two kids with his wife Yvonne McGuinness; Malachy, 17, and 16-year-old Aran.

While it's thought Malachy has previously shown an interest in music, Aran has long been following in his father's acting footsteps.

At the age of 11, Aran starred as the title character in the play Hamnet, which toured around Dublin, London, New York, Boston, Brisbane and Hong Kong.

He later starred in the 2022 film Lola alongside The Witcher's Emma Appleton; but Aran's newest venture will be his first feature film.

Directed by Taika Waititi (the brains behind films like Jojo Rabbit and Thor: Love and Thunder), Aran will play Rick in the upcoming movie, Klara and the Sun.

Based on the New York Times bestselling novel of the same name, the film is about a robot girl who is designed to prevent loneliness that tries to save a heartbroken family of humans.

Aran joins Jenna Ortega and Amy Adams in the film. The Wednesday actress will star as robot Klara, who is purchased for teenager Josie (Mia Tharia). Adams plays Josie's mother.

The teenager has some big shoes to follow in when it comes to his famous father, who was recently nominated for an Oscar for his role in Oppenheimer.

The nomination comes as his first ever Academy Award nod.

Speaking about the nomination, the 47-year-old said he doesn't worry about if he'll win or not.

"I genuinely don't think about that," Murphy told the BBC. "It's kind of wasted energy. I just feel so thrilled and humbled to be [mentioned] in the same breath as all those wonderful actors."

Murphy added: "I know everyone says this, but you never go into making a film thinking about awards. That’s not what we do. It’s impossible to make a film that way.

"But, when a film connects with audiences like this particular one has in a way that none of us could have anticipated... it’s hugely flattering and hugely humbling and it’s lovely to see that."

Murphy's Oscar didn't come easy. The father-of-two had to learn a whopping 30,000 words of Dutch for his portrayal of J. Robert Oppenheimer.

Sharing his technique of how he learnt the language, Murphy told NBC Insider: "You break it down and say, 'Alright, we need to work on this today.'

"I used to set aside, 'I'll work on this for a week and I'll work on that for a week.'"

A+ for commitment.
