Neds has made its UK debut at the London Film Festival.
The film stars 17-year-old Scottish newcomer Connor McCarron. He plays John, a teenager in Glasgow in the 70s, who shines at school but falls in with a gang of "Non-Educated Delinquents". Director Peter Mullan plays his violent alcoholic father.
Mullan hopes the film, about youths who drop out of education and turn to violence, will deter young people from such behaviour.
Speaking at the film's premiere at the BFI London Film Festival, Connor said: "Hopefully real Neds can watch it, real Non-Educated Delinquents can watch it and learn from it. They can say 'What's the point?'."
But the young teen confessed he had enjoyed filming the violent scenes in the dark, gritty drama.
He said: "The reality of fighting is terrible, but the fight scenes, to film, they were pretty good, they were really fun."
Connor won the best actor award for his performance at the San Sebastian Film Festival and he has also been nominated for Best British Newcomer at the London Film Festival.
This is the first time McCarron has acted - he went along to the audition after his dad read an interview with Mullan in the local paper, in which the director said he was looking for kids for a new film. Almost all the young cast were picked up from the 300 or so who showed up, and their audition photos flash up during the end credits.
