Movie violence associated with sex, alcohol and tobacco use

Nearly 90 percent of the top-grossing movies over a 25-year period show main characters acting violently, and in 77 percent of the movies those characters also engage in sex-, alcohol- or tobacco-related behavior, a new study has shown. The study published in Pediatrics, by researchers at the Annenberg Public Policy Center, found that more than half of the biggest PG-13 movies featured a main character acting violently and involved in either drinking, sexual behavior or smoking within a five-minute segment.

More gun violence in top PG-13 movies than in biggest R-rated films

The amount of gun violence in the top-grossing PG-13 movies has more than tripled since 1985, and in 2012 it exceeded the gun violence in the biggest R-rated movies, according to researchers at the Annenberg Public Policy Center and the Ohio State University. The overall rate of violence in the biggest box-office movies has more than doubled since 1950, the researchers report in "Gun Violence Trends in Movies," published in Pediatrics.
