How thriller conventions are used in Insomnia and in Memento.

In both movies, the titles appear over a background with blood. In Insomnia, a withe title appears over a close-up shot of a stain of blood seeping into a piece of fabric that then turns into a blackout, and in Memento over a close-up shot of a hand holding a polaroid photograph of a dead men with blood around him. That scene is going backwards. In both films there are close-up shots of the blood but in Insomnia there are also establishing shots that show an exotic landscape (ice).
In Memento there are lots of close-up shots : man's face, camera, blood, the bullet, glasses, dead man's head. and then there is a medium shot of the man looking at the dead one and everything starts going backwards faster with a tension building music and suddenly he appears on a motel in black and white to create the atmosphere and disorientes the audience.
In Insomnia, the music moves to a crescendo as the editing cuts between shots and during all the opening secuence there are close-up shots of the blood in the fabric, and thestablishing shots of the view of the snowscape they have from the plane, and then the vision blurres and turns again into white screen. Then a man apperars rubbing his jacket to remove the stain of blood so that the audience think that he has murder someone and he is trying to hide it, intrigueting the audience.
