Cillian Murphy firmly corrected an interviewer who called him a British actor

Oppenheimer is finally out in cinemas, with many film lovers flocking to the cinemas to watch Christopher Nolan's latest offering.

The movie tells the story of of American scientist J. Robert Oppenheimer (played by Cillian Murphy) and his role in developing the atomic bomb which was used in World War II - something he earned the title as the ‘father of the atomic bomb’ for.

While the likes of Emily Blunt, Robert Downey Jr., Florence Pugh and Matt Damon are involved too, the attention has been firmly on Murphy in recent days and the weeks leading up to the release of Oppenheimer.

With Murphy bank in the spotlight following the conclusion of BBC's Peaky Blinders, many have been asking that one question that seems to pop up time and time again... is Cillian Murphy British?

Well, it is a question you certainly won't want to be asking the actor as he is in fact Irish, as many interviewers over the years have found out.

The perhaps most famous interview comes from when Murphy was interviewed ahead of the release of Inception back in 2010.

While sitting next to Tom Hardy, Murphy's co-star in the Nolan-directed film, the interviewer claimed the acting pair were both British.

Well, this is when Murphy's blood started boiling, to which he instantly replied: "No, I’m Irish."

But the interviewer really wasn't taking the hint, as he continued by saying: "Yeah I know, British."

Murphy wasn't going to back down though was he, as he instantly replied: "No, no, no, I’m Irish."

The interviewer still wasn't taking the hints, though at this point he was surely just winding Murphy up, as he said the actor was from an 'area of North Europe'.

And once again, you can predict Murphy's reply, he said he was Irish, of course.

While he may be Irish, Murphy actually spent a bit of time living in London, though his home did eventually come calling.

Back in 2015, the Peaky Blinders actor moved his family back to Ireland because his kids had 'posh English accents'.

Speaking to Dax Shepard on The Armchair Expert podcast in 2022, Murphy said: "We wanted the kids to be Irish. They were sort of at that age where they were pre-teens and had very posh English accents and I wasn’t appreciating that too much! So we decided to come back.

"We were in London for 14 years, both our kids were born there and we only came back to Dublin in 2015.

"It’s kind of an Irish story to move away, do your thing and come home, that seems to be a common narrative for Irish people."
