Daisy Edgar-Jones has admitted that Marianne's famous hairstyle in Normal People was the result of a "break-up haircut" after she lost out on a part.
The 22-year-old English actress shot to fame as the star of the adaptation of the Sally Rooney novel of the same name.
Her haircut, featuring a heavy fringe, has developed a cult following to rival Connell's chain, the jewellery sported by her co-star Paul Mescal.
There is now an Instagram account dedicated to "Marianne's Bangs", as there is to the chain.
Edgar-Jones told the September issue of Harper's Bazaar UK: "It's so funny. I got the fringe as a sort of break-up haircut after I came really close to a job and didn't get it.
"The next week I had another audition for [the television series] War Of The Worlds and got the part. I can act better with a fringe, it's my secret power!"
Edgar-Jones said it was "bloody terrifying" to take on the role of Marianne, adding: "When I got the part, I was very excited. Then I had the fear settle in, the imposter syndrome of thinking, have they actually got it wrong?
"I learnt a lot during filming about being more confident in my voice and not feeling like I have to quieten."
Reflecting on the show, she said: "I'm really proud of it. It's so raw and honest. We're not just seeing a glossy, honeymoon portrayal of love, we're seeing the rust of life. It's the truth of growing up."
She said this was reflected in the sex scenes she shared with Mescal, saying: "It was about creating a real friendship with Paul so we could trust each other. I'm lucky he and I understand each other and have a very similar sense of humour.
"Neither Paul nor I are ever sexualised in those moments. It's just a story of young love."
Edgar-Jones added she now has ambitions as well as acting, saying: "Ultimately, I'd love to direct. I'm really fascinated by film-making and cinematography.
"As much as I love a performance, I also appreciate how a choice of lens or music can elevate it to a different level."
