They found that adolescents with the highest exposure to alcohol use in films were 1.2 times more likely to have tried alcohol than those least exposed, and 1.7 times more likely to binge drink.
Those with the highest exposure were also 2.4 times more likely to drink weekly and twice as likely to have alcohol-related problems than those less exposed.
The study authors suggest a review of film-rating categories and that alcohol ratings for all films may help reduce alcohol consumption in adolescents.
Between 1989 and 2008, 72 per cent of the most popular UK box office films depicted alcohol use, but only 6 per cent were classified as adult only.
