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

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."

And now, the 'Peaky Blinders' actor is looking forward to some time off when he can in order to "live as a human being", which he believes will only serve to make him a better actor.

He said: "Honestly, I just want to have a rest. I really enjoy being at home and not working. I enjoy going to the shop and walking the dog and watching movies. I haven't been able to do that at all. My ¬creative output gets used up very quickly.

"I think you need to live as a human being to portray a human being. The life I lived for part of this year was definitely not reality."
