Editing in thrillers

Thriller movies use complex editing to ensure that the audience stay interested in the piece they're watching a good example of how editing and camera angles can be used can be shown in the movie:  the Bourne Ultimatum which utilises these scenes to make the most dull of scenes much more interesting to watch.

The main character is the focus of this shot

In this shot above Jason Bourne is the character the editors want the audience to observe and this can be told by the way the focus is only directed to the characters face and the rest of the image is faded out making looking away pointless because you can't properly see the background or make out faces that are important.

 

Another image showing how important certain characters are

Looking at this character  you can also tell he is important by the way the camera shows different focuses and the direction he's looking at which almost looks as if he's looking towards the camera.
