Smoke screens.

Where there's smoke, there's fire. A University of California professor is burning up over how often actors light up on the big screen. Stanton Glantz studied nearly 800 flicks from the past five years and found that nearly 80 percent of movies rated PG-13, and half of G-and PG-rated films, featured tobacco use. Professor Glantz points to smoking scenes in movies like 102 Dalmatians, Holes and What a Girl Wants. What the professor wants is the Motion Picture Association of America to take smoking scenes into consideration when rating films. "Smoking should be treated by Hollywood as seriously as offensive language," he says. He hopes such a policy will get more R ratings for movies that feature people puffing. We just hope kids are smart enough to know that movie-making is a creative process, not a smoking advocacy campaign.
