Casey Affleck believes that billboard adverts for movies should be given ratings.
The actor has hit out at the way that movies are advertised and believes that some of the graphic nature of those adverts should not be seen by children.
The actor told The Guardian: "The advertising of films and TV is gross. There's a rating system for films. I think there ought to be a rating system for billboards.
"I have kids, and there are things I look at where I think, I do not want that image in my head, let alone my kids' heads.
"Horror films. All those - like Saw. Your average run-of-the-mill PG13 action film, there's blood spattering, or knives [in the advertisements]. It's all you see.
"That kind of depiction of violence is all around us. And it does a lot more harm."
Affleck is back on the big screen next month with his new movie The Killer Inside Me, which is directed by Michael Winterbottom.
The movie is based on the novel by Jim Thompson and has already caused controversy with the level of violence.
The Killer Inside Me is the first movie for Affleck since the critically acclaimed Gone Baby Gone.
