In the opening sequence to Se7en there is many techniques used to draw you into the film and make you want to watch the rest of the film. In the titles sequence as long as the titles appearing and revealing people that had something to do with the film, there are many close up shots of normal house hold objects, like books and paper and pictures. However, the way the creator has filmed these objects makes them very scary and spooky. The mise en scene used for the opening scene is very carefully chosen, as all the objects filmed are very dark, dull and boring, which creates tension for the audience as they want to know why they have been portrayed like that. The use of close ups is also very crucial to the opening scene as it zooms right in to the object and makes it seem out of context and spooky. The fact that the there are hands in a lot of the shots makes the audience feel creaped out as they do not know who's hands they are, and they want to find out who's hands they are. The way that the titles are shown on the screen are even scary, as they look like they have been roughly scribbled and they they disappear eerily also as they just fade out into the dark and shadowy background, which also acts as an aid to create tension because the colour black is very scary and in a way portrays fate and death.

Also more important information like the release date and the age rating is narrated on the trailer so that viewers can make sure that they see it. In the trailer there is a montage of clips which help to portray the fast paced and action packed film, if it was one continuous clip it would be hard not to tell the whole story.

In the trailer there is some written words that appear on the screen, the usual ones, like release date and actors and then there are certain words that are repeated on the screen and this is used to draw the viewers attention. Because the words repeated are in red, this automatically creates tension, as red is seen as an uneasy and unflattering colour. So seeing this, makes the viewers want to know why it is written in red.
