Rob Reiner，co-founder of Castle Rock Entertainment，was greadtly surprised when he saw his studio's film Proof of Life. “Wow，why is Meg Ryan smoking up a storm?”Reiner says. “It didn't add to the plot. ”Fourteen months later，Castle Rock has a policy of discouraging tobacco use. Any actor，director or screenwriter who wants to depict it must first meet with Reiner. “They have to make a really good case. ”he says. “Movies are basically advertising cigarettes to kids. ”Movie characters light up more often than people do in real life，argues Stanton Glantz，a professor of medicine who has launched a“Smoke-Free Movies”newspaper ad campaign. His study found that on average the 20 top-grossing films featured 50%more instances of smoking an hour in 2000 than in 1960. And an American Lung Association survey discovered that 61%of the tobacco use in films last year occurred in movies rated G，PG and PG-13. With teen smoking up dramatically in the past decade，a movement is building to hold Hollywood accountable. So Glantz says，“The entertainment industry is in denial. ”

B．ut it's getting an education. Susan Moses，deputy director of Harvard's Center for Health Communication，and Lindsay Doran，former head of United Artists，have been going from one studio to another. They hit the bosses with hard facts：a million teens a year become daily smokers，and a third of those will eventually die from tobacco-related illness. When Doran and Moses met with executives from Imagine Pictures，says Doran，“They said，‘Smoking is not in any of our scripts. ’But then they called the next day and said，‘We looked，and it's everywhere. ’”Karen Kehela，co-chairman of Imagine，recalls trying to take smoking out of one script. after the meeting，“but the actor insisted on smoking,”she says. In fact，many movie stars can't leave their cigarettes in the dressing room. “Actors who smoke look for any reason to integrate it into their characters，”Reiner says. “You have directors who don't care about the social implications or are yielding to the actors. ”
