Enemy of the state:
Throughout the clip the main camera angle used were Ariel/Birds eye views. The view from above gives the impression that people are being spied on with the frequent appearances of props such as CCTV cameras and footage from stores and police cars .The camera movement of panning well know political buildings such as the white house help the audience to identify with potential sub-genres. The fast passed editing helps to convey suspense’s with so many images flashing before the eyes of the audience they start to think about questions and try to come to conclusions about what will come next. The sound at the beginning of the clip is very fast paced with the distinctive sound of police sirens as the clip progresses the sounds of violins & strings become apparent which evoke empathy before silence is transitioned into the next scene before the clip comes to an end. Suspense is created in the clip by the constant movement and also the frequent changes in sound which change the mood and tempo of the clip .
