Arguably the most famous haircut on terrestrial TV (what an accolade), Cillian Murphy's closely-shaved fringed crop from Peaky Blinders has become something of a national obsession over the last couple of years – but the man who actually wears it doesn't get what all the fuss is about.
In a new interview with Shortlist, the Dunkirk actor discussed his unwilling influence on the hair craze, saying: "People like the undercut thing; people go to the barber and ask for a 'Peaky cut.'"
"It's crazy that people like it, it's not grown on me in four years now. I normally keep my hair long."
Referencing its popularity among the trendy London set, he added: "But do they realise, the people in turtlenecks in Hackney with this haircut, do they realise it was styled this way to prevent lice?
"Tell 'em they've got the lice cut, see what they say then."
Will do, Cillian.
As well as discussing the burden of having the coolest hair on TV, the 41-year-old also revealed that he isn't planning any repeat viewings of Dunkirk.
"I'll see it once", he said, adding: "I don't know anyone who pores over their work because the impulse is always the next – the next piece I do will be the best piece I do. To an actor, nostalgia is death.
"When you look at your work from 10 years ago and think that was the apotheosis, well, you're f***** really. It's got to be forward thinking."
Shortlist is out now.
