"

The tobacco industry has had a long relationship with the entertainment industry. In silent era movies, back-lit smoke was often used by filmmakers to create sense of mystery and sensuality in a scene. Later, cigarettes were deliberately placed in the hands of Hollywood stars as an early phase of product placement,[1] until health regulating bodies tightened rules on tobacco advertisement and anti-smoking groups pressured actors and studio executives against such tactics. Big Tobacco has since been the subject focus of films such as the docudrama The Insider (1999) and Thank You For Smoking (2005).
