se7en trailer analysis

conventions
voice over- a voice over is used throughout the trailer , this is uncommon in trailers nowadays but when this film was out they were very common this shows how the conventions of thrillers and films a like can change throughout the years . the voice over takes away from the thrill factor off the trailer because it adds a sense of familiarity to it by adding a normal persons voice , without the voice over it would completely draw the audience in but because of it leaves them still not fully engaged with what is going on in the trailer.it also uses a lot of red text throughout the trailer especially when the seven sins flash up , they are all in red , this is gives the effect of evil and blood because the colour red is the colour of evil and so also the colour of blood , this fits into the film as those who commit the sins are killed .

sound
There is many sound effects throughout such as gun shots and ticking clocks , these sounds fit the film because it is about murder and they have a matter of time to catch the killer .There is also music that speeds up in beat as the trailer goes on and eventually keeps a steady up pace beat as the trailer is reaching the climax and it becomes more intense  and then cuts off as the two main characters share a very important piece of dialogue when the rookie asks "have you ever seen anything like this" to the veteran and he says no even though he has been the game a long time which shows just how bad it really is.

editing
there is a lot of flash cuts and white flash cuts this gives the effect of rushing and not being certain what is happening just like how the characters are acting in the film , running round and trying to figure it out .There are also titles throughout the trailer of the deadly sins that remind us what is next in the murders. at the beginning it is slow paced, it uses fade to blacks and is very dialogue based but as the trailer goes on the editing is more flash cuts and more action in the clip based, but then right at the end it slows down to focus on key points and goes back to fade to blacks.

camera
its uses a reverse zoom shot when the veteran detective is investigating the crime scene so you gradually see more and more of the horror he is witnessing this gives the effect of suspense because you don't know what you're about to see. A lot of close ups are used to see the characters expressions when they see something in one off the crime scenes this gives us an insight into what the character might be feeling by the way they look and gives an effect of immersion into the trailer because you can almost feel the same emotions as the character on screen .

mise en scene
Morgan freeman`s veteran character dresses in very formal dress such as a suit with a proper tie and long coat with a hat where as brad Pitts character the new detective wears different clothes , still s shirt and tie but a skinny tie not done up properly and a leather jacket , this shows that he is a new kid on the block because he isn't dressed as smart or dressed differently to the veteran.There is a lot of dark lighting and red colors because the darkness is uneasy and fits the atmosphere and mood but also a lot of neon colors.
