Documentaries are important in cinema because they can tell stories. Their stories, however, are true. There are a few different purposes filmmakers can have for creating a documentary. In the categorical documentary form, the filmmaker tries to convey a lot of information, then categorizes that information so that it is easier for the viewer to understand. In rhetorical form, the director is trying to persuade the viewer to think a certain way. Say no to plagiarism. Get a tailor-made essay on "Why Violent Video Games Shouldn't Be Banned"?

It's simply implied through the stories the artists tell. While they simply sing behind the “star”, they are truly bringing a new light to the stage through their voice, their style and their emotions. Many of them are real stars, which was made clear by the film's emphasis on their vocal abilities and stage presence. There was definitely repetition in the film. The creators used notable musicians including Bon Jovi, Sting, Stevie Wonder and many others to lend credibility to the message that backup singers are more than just backups. There was variety in that it focused on multiple artists and didn't spend too much time on one artist for more than a few minutes at a time. The general outline of the film began by introducing us to each of the artists first. We got to meet them individually and find out how they got started in the industry. Then we learned a little about their high point in the industry and also heard about their struggles (like having to work as a cleaner to get by) before falling back to the background. The singers this film focused on changed the role of backup singers from just singing "oohs" and "aahs" to singing hooks to multiple songs on major records and completely changing the sound of some notable musicians' works.
