That can range from little white lies-trailers for musicals often don't show characters singing and trailers for foreign films often don't show characters talking because that might turn off moviegoers who don't like musicals or foreign films-to the frequent complaint that trailers sometimes show scenes that are not in the finished film.
The current "Cheaper by the Dozen 2," for instance, includes a couple of such moments. But that's not necessarily an attempt to deceive. Trailers are almost always assembled before the movie is completed, so it's often impossible to know what will make it into the movie. There's a trailer in theaters now for "Dreamgirls"-a movie that hasn't even begun shooting.
