Watch Oliver's film above

A budding teenage filmmaker’s idea for an antismoking film has been turned into reality after he won a national competition.

Oliver Sabine, a 15-year-old pupil at Dorothy Stringer High School in Brighton, entered the competition run by Cancer Research UK and Channel 4’s 4Talent to create an online video campaign against smoking.

The hard-hitting film shows a teenage house party where a boy sees a pretty girl in the flashing lights.

As the girl continues to smoke and the party progresses the girl turns into a wrinkled, unattractive old woman and the look of shock from the boy is captured on film.

Oliver’s idea struck a chord with competition judges who turned it into a 45-second film.

He said: “I’ve loved this experience.

Coming up with the idea of the film was easy.

“It’s obvious that smoking isn’t good for you.

“Going to London to work my ideas into a full treatment and getting the film made has been great.

“I’m hoping to continue to work in the media.”

The other two winning films show a young girl coughing up a lung after a night of partying and a young man who pays to die in a slaughter house.

Teenagers from across Britain were asked to enter their ideas about smoking to create a highimpact film that would make other young people sit up and take notice.

The top ten were shortlisted from more than 1,500 entries.

After a two-day workshop involving an industry master class, the ideas were developed into movie proposals.

They were tested in focus groups and a panel of leading tobacco researchers and filmmaking experts chose the winning selection.

James Estill, senior producer for Channel 4’s 4Talent, said: “To create messages on this notoriously difficult subject that young people can relate to was never going to be an easy task. But again, the creativity demonstrated by the winners has produced a fantastic and diverse range of films.”

Jean King, Cancer Research UK’s director of tobacco control, said: “It’s important that we involve teenagers in developing a relevant anti-smoking campaign for a teenage audience.

“Two-thirds of smokers start before they turn 18 and it’s vital we work to reduce this figure.

The earlier someone starts to smoke, the more difficult it is for them to quit.

“We’ve been thrilled that so many teenagers entered the competition and the winning films are some of the most powerful I’ve seen from this age group aimed at their peers.”
