Ryan Gosling had to teach fellow A-listers how to pronounce her name but Saoirse Ronan has said she'll never change it.
The 21-year-old admitted she used to hate her Irish name when she was younger but grew to love it.
"I would never change my name," she said.
"When I was a child and nobody else was called Saoirse, I thought, 'Oh, I'd like a normal name', just because I was a kid.
"But the older I got, I decided I was never going to change anything for anyone," she added.
The Carlow native has been an actress since childhood and said she got some invaluable advice from American rocker Patti Smith.
They met at a party for 2013 sci-fi movie The Host when Saoirse was 19.
"I think she came along just kind of when I needed her, really," Ronan said.
"She was kind of like a guardian angel or something.
"We were doing a lot of press and I was still getting used to all of that, and she just said 'hello' to me and took my hands and looked at me and said, 'Just remember, it's about the work - it only ever can be about the work, and as long as you remember that, you'll be fine.' It was amazing," she added.
Ronan's performance in Brooklyn has been garnering Oscar buzz but she said it was her hardest role to date.
"It was the first time I felt fear," she told the Hollywood Reporter.
"There was nowhere to hide. I wasn't in heaven, I wasn't a vampire, I wasn't an assassin.
"This was the hardest thing for me, to be able to play someone whose identity was so similar to mine.
"I mean, this felt like it was my identity, and I was still kind of coming to terms with that myself.
"I really didn't think that I'd get through it most days.
"That's why it's so amazing that this [the celebration of her performance] is going on.
"To be able to walk through that fire and have all of this happen? I'm still pinching myself."
Oscar nominations are due to be announced on January 14.
