The best quote in L.A. Times reporter Robert Welkos10.26 piece about red-band trailers comes from Chicago-based marketing blogger Chris Thilk. Each red-band trailer, Thilk has written, becomes the “equivalent of sneaking a Playboy into junior high homeroom.” And the opposite effect kicks in when you try to shoehorn the essential appeal of an R-rated film into a “green” PG-13 trailer. “If you’ve got an R-rated movie and you’re creating a PG-rated trailer,” he tells Welkos, “I’m not going to say you’re misrepresenting the film, but you’re certainly watering it down.”
