How does Nolan convey memento as a psychological thriller?

Nolan convey memento as a psychological thriller because instead of a regular film it represented backwards which is non-linear.

The film has to be broken down because the film is very complex to understand as it the start if the film is the ending of the film this is because the character has a short term memory so the audience only remembers what the character remembers, which why it is non-linear.

Sound

The music shows tension because it is non-diegetic, in addition it reveals sadness because the sombre key. There different sounds which are diegetic these sounds have been emphasize for example the sounds of a gun firing by the sounds being emphasize it gives the notion that they are the only two people in the building because of piercing sounds being used this also provides the audience with tension because it creates a dark and mysterious scene to the viewers eyes.

Mise-en-scene

The mise-en-scene helps to give a clear clue in each shot to what the genre is it gives signifiers such as one of the first shots contain blood which hints that it is a thriller because it signifiers that it the film contains murder, because of the blood which gives us the impression of conventions such as murder, the connotations of the darkness shows the genre of the film also. This gives out a feeling of negitivatity this is partly because it is a sad movie for the reason that he cannot create new memories, plus he is trying to discover the person who murdered his wife. Because the film is non- linear it adds to the mystery of the film because it very hard to understand this is because we are seeing what the character is remembering or doing in the present time.

In the opening scene of Memento shows a close up shot of a photograph being held by Lenard by seeing this shot makes the audience feel hesitant about what is happening. As the shot of photograph stay in the shot for a long period of time it could confuse the viewer because it seems as the character need a long amount of time to take the image in. Because this film is backward it may take some time to realise it if the film has never been watched by the viewer but Nolan uses techniques such as making the photograph fade which gives the audience the hint that the film in backwards. 

The Happening

The music sets the scene at the start of " The Happening" this is because it creates tension and gives us an impression of mystery because we not know what is going to happen. at the beginning it is very stereotypical this is because they are in New York in central park walking their dogs and excising (jogging).

the close up shots show conventions such as high wind speed which tells us that things aren't calm. two characters are having a conversation about death which gives us the impression of depression and the mise-en-scene of death which helps us to know it is going to be a thriller and a mixture of horror. music plays whilst the character hears more conventions such as screaming to indicate more that this is going to be a thriller.

we cant hear her talking clearly which gets us wondering what is going on and what she is shock about.
this film presents odd types of reactions and creates and weird atmoshere this is because her friend kills her self but she just has a blank stare in her eye as she doesn't care that she has done this.
the dog from the start is now roaming freely which confuses us because we wonder where he owner has gone and "why the dog is off it lead" or " where is it's owner".
in my opinion think that is is good film and i really enjoyed it but the ending wasnt so good because it was a expected end.
