This trailer uses different effects to attract its target audience and make them want to watch the film. One is the soundtrack, it uses a song from the sound track to interest people that already like that music into wanting to watch the film as it has this style of music in basically widening its target audience / boosting its box office figures. It also uses a very famous singer which is what this film is about as the main character to play himself this gives the trailer a bigger sense of realism and once again boosts its target audience as this famous rapper will already have a target audience from his music. it also uses different action shots from the film to entice the viewer into wanting to watch the actual film. Even though this trailer basically tells the story it misses vital parts from the story so it doesn't show the viewer to much it also doesn't show the ending of the film which will also entice the viewer into wanting to watch it.
