Cillian Murphy warned his career is under threat because of his teenage son

Cillian Murphy's friends have warned his career is under threat because of his own son.

The 'Oppenheimer' actor - who has Malachy, 19, and Aran, 17, with wife Yvonne McGuinness - admitted his younger child is already "really good" and though next year he will appear in an adaptation of 'Klara and the Sun', he insisted the teenager has the talent to prove he isn't just a nepo baby.

Cillian told Telegraph magazine: “It may not be the thing he does, but he’s really good at it.

“One of my friends saw him in a play and said, ‘Cill, he’s better looking, he’s a better actor, he’s younger and he’s taller. You’re f***ed.’ We’ll see.

"People are smart enough to judge you on your talent. There’s no way any kid will get by on nepotism alone. Everyone in this business gets found out unless they’re good, and he’s a good little actor."

However, the Oscar-winning star insisted he and his wife won't be pressuring Aran to keep acting.

He added: "But we’re not putting him under any pressure. If he decides to become a musician or a poet or a farmer or a chef, that’s up to him.”

Cillian won a string of awards this year for his work on 'Oppenheimer' but he admitted he hasn't properly processed his success yet because he's worked relentlessly since then.

He said: “I haven’t properly reflected on it all. I went straight back to work. I don’t know if that was the correct thing to do or not, but I did.”
