Genre is important for both film producers and audiences. For producers, specifying a genre helps attract a target audience and impacts marketing. People who enjoy a particular genre will support films of that genre. For audiences, knowing a film's genre prevents confusion and helps determine if a film appeals to their tastes. When making an action/adventure or science fiction film, genre informs scene setting, effects, and props used. Following genre conventions meets audience expectations and attracts the target viewers, while breaking conventions risks losing the elements that genre fans enjoy.
