Katie Jarvis has confirmed that she had never acted before starring in new British movie Fish Tank.
The actress was asked to audition for the lead role in the Cannes Jury Prize winner after being spotted by a casting agent having an argument with her boyfriend at Tilbury railway station.
Jarvis told the BBC: "It was really, really nerve-wracking, to be honest. I'd never done any drama in school even. I was always too embarrassed to act in front of people. I never liked having my picture taken.
"But when I went to do Fish Tank it boosted my confidence right up and I thought, 'Sod the cameras', and just stuck my head right into it and got into it really quickly."
She added: "After I'd signed the contract I knew there was no going back from there. It was a bit weird for me really because I knew I had to do well.
"Plus I had a really good relationship with the director Andrea [Arnold], so I wanted it to turn out well for her sake as well as my own because she took a big risk on just picking me from the street in the first place."
