Opening Sequence analysis - Psychological Thriller

As me and my group have now decided on what genre of film we wish to produce, which is a pyschological thriller, I will soon be posting some opening sequence analysis. The first one will be a general idea of how the opening sequence of a psychological thriller goes, and then the second will be in a lot more detail. This would enable me, and my group, to establish certain characteristics of opening sequences of pyschological thrillers which we can use to come up with some ideas to infuse into our own opening sequence. After conducting this analysis, this will help my group with how to lay out the opening sequence i.e. when to insert credits, what soundtrack we should come up with, how many of the cast we should establish during the course of the short sequence. This would allow us to create the atmosphere for the audience that they are actually about to watch a thriller. With an opening sequence to a thriller, especially a psychological thriller, it will always make you want to watch the rest of the film. This is done by the soundtrack, the shots of the cast and the location of the shot. You could also be enticed to watch on if you are provoked into making a judgement upon some of the characters, therefore leading you to watch the rest of the film to see if your judgement of the characters was actually correct. This is something that me and my group could use to our advantage while creating our opening sequence. The two films I have chosen to conduct my opening sequence analysis are Law Abiding Citizen, and Se7en.
