Disney Wants to Ban Smoking From PG-13 Movies
Disney CEO Bob Iger announced that film that target a child audience will not feature smoking in the future. That includes all films with a PG-13 rating and below, so basically all big blockbusters under the Marvel or Pixar banner (and also the new Star Wars films). Exceptions would only be made for historic characters in case they do appear in such films and did really smoke in their time. "R" rated films are not affected by this order but they are rare anyway.
Iger continues that he does not intend to make this decision a rule (voluntarily or not) in the MPAA's guidelines (where Disney is a member) so that other film companies would have to implement that in their film, as well. He doesn't want to tell other studios what to do. But when one starts, it surely just a matter of time until there are only non-smokers left on the cinema screen.
