Irish actress Saoirse Ronan may be just 19 years old, but like all Hollywood starlets, she recruited the help of a body double for her latest film role.
Welsh set designer Laura Harold (33) praised the Carlow native's down to earth nature while filming post-apocalyptic romantic thriller How I Live Now.
The mum of two is originally from Dublinand the blondes were a near identical match, despite the age gap.
“I had a friend who couldn’t do it and I got asked to send some photos in to an agent who was helping cast How I Live Now and I matched up almost," she told Wales Online.
“Obviously we are very far apart in age – I’m 33 and she’s 18 or 19 but when it came to measurements, we were fine.”
“The next Monday I had a chauffeur show up on my door."
Harold explained that she filmed quite a bit as production regularly filmed two scenes at once, where Saoirse was required on camera.
“I really had to get my running shoes on," she explained.
“Most of it was running through brambles and running up a hill.
“You get scratched up and bruised up and there were times when I was working so hard I felt physically sick and that was quite hard work on my body."
Oscar-nominated Saoirse reportedly 'fell in love' with co-star George MacKay during filming of How I Live NOw.
Her American character, Daisy, moves to England to stay with her eccentric cousins and eventually falls in love with her relative Edmond, played by MacKay.
Director Kevin Macdonald revealed that he couldn't have been luckier during the course of filming when it came to his stars' romantic chemistry, as art was imitating life.
"What happened during the course of film, and I'm hoping that I'm not speaking out of turn, is that they fell in love and it was very easy," he said.
"It was Saoirse's first proper boyfriend and, in a way, I think she was living through the same thing that the character is going through.
I suspected what was going on but they kept it very quiet," he told The Independent.
