Would "Casablanca" have been rated XXX?

Depictions of smoking in movies will now be a factor when deciding what a film's rating will be, possibly making a PG-13 movie R-rated, the Motion Picture Association of America said yesterday. The policy affects only new movies.
Along with violence, depictions of sex, adult language and other content considerations, ratings organizations will examine new releases to determine if they glamorize smoking or if it is pervasive through the films, even among adults. Underage smoking has always been considered when rating a film.
"Clearly, smoking is increasingly an unacceptable behavior in our society," Dan Glickman, chairman of the motion picture association, said in a statement. "There is broad awareness of smoking as a unique public health concern due to nicotine's highly addictive nature, and no parent wants their child to take up the habit."
A number of groups have called for almost all movies that depict smoking to automatically receive an R rating, a plan the movie studios oppose. Children under 17 are not allowed in R-rated films unless they are with an adult.
Cigarettes were once an indispensable movie prop -- something for actors to do with their hands and to establish character traits, such as "edgy" and "rebellious." Sex symbols such as Humphrey Bogart and Bette Davis helped make smoking seem sophisticated. A leading man was not a gentleman unless he lit a lady's cigarette.
