An opening sequence is designed to:

• establish character and narrative context
  


• set up a degree of curiosity or question that will be answered later on in the film
  


• help the audience understand location, character and purpose
  


• cut between credits and action

The opening of Se7en.
As soon a s the opening of Se7en starts it doesnt show any characters it shows an object, a book. It right away shows credits when the image is still showing this alredy shows mystrey. Then the sequence show Match on Action and goes to a black background and then shows credit saying its an Arnold Kopelson production. i thought se7en's use of music and sound effect was very clever as they were repetitive.
I found se7en didnt really give the audience help in understanding the location and the characters and their purpose as there was not dialogue and or any narrative voice. However i found that se7en did set up a degree of curiosity of question that will be answered later on in the film.
I found it very effecting that in the opening odf se7en you never saw the characters face and this is a good convention as it gives mystery for the audience this gave an confusing affect but alos would keep the audience interested.

Catch me if you can
As soon as someone would watch this the fiorst thing they would notice is that the opening is animated. I found this very interesting and think an audience would find this interesting as it is different way of showing what may be in the film its self. I found that it all links together and is never stopping which would keep a viewer interested throughout the short period. I found that catch me if you can built up curorisity as a man is running throughout it and this could be question, why is he running? Even though i thought it was effective in showing animation, I dont hink the opening sequence shows help for the audience to understand location, character and purpose as it is animated and you do not get to see the real characters in life and show there surrounding s which would have been good to show to help the audience with their understanding.
