From the opening scenes of the movie I learnt that they all have different styles of showing viewers what the movie might be about. For example sin city had a completely different style of filming , it had a black and white and red effect. 21 Jump Street had an opening scene of following a character to another setting. I learnt that it doesn't matter how you show the audience what the film is about just as long it grabs their attention. Sin City grabbed the audience because it has a mysterious opening the audience wants know more and why that woman got shot and who she is. 21 Jump Street grabbed the audience attention because it was ironic that there was Eminem music playing and guy that's trying to look like him, this is funny to the audience and makes them want to laugh and watch the film more.
