Anti-smoking groups that have long complained about scenes in movies showing the stars smoking will apparently get a big boost from a new British law that takes effect Sunday barring smoking in enclosed public places. The law will apparently also apply to all film productions in the U.K. Under the law, producers may apply for exemptions in the case of productions where smoking is "integral to the plot or storyline." But London officials recently rejected an application for an exemption in the case of a forthcoming play about Pope John Paul I in which a cardinal is seen smoking, forcing a rewrite of the scene. An actors' union spokesman said later that authorities would only allow exemptions to productions about real-life persons, like Winston Churchill, who were known for their smoking.
