Listen up, Hollywood!

At a closed-door meeting in Hollywood on Feb. 23, public health experts from Harvard and Johns Hopkins presented scientific evidence of the harm to children associated with the depiction of tobacco smoking in movies. The meeting was convened by the Motion Picture Association of America (MPAA). Approximately 40 executives attended from MPAA, the leading film studios, the Directors Guild, the Screen Actors Guild, and the National Association of Theatre Owners.

In prepared remarks at the meeting, Dean Barry Bloom of the Harvard School of Public Health urged the MPAA and the studios to take substantive and effective action to eliminate the depiction of tobacco smoking from films accessible to children and youths.

Summaries of presentations made at the Feb. 23 meeting were made public today on the web site of the Harvard School of Public Health.
