Another function of a premiere is to measure the success of the movie. Producers, directors, writers, and actors observe the reactions of the audience to see if line delivery came out right or if special effects were worth the effort. A third function of a movie premiere is word-of-mouth advertising. The organizers of a movie premiere work hard to make sure the paying audience is thoroughly entertained. They want these viewers to tell the world what a great movie it is. Even if a movie is not that great, the viewer might still think it is if he or she has had a truly positive experience at the event.
