Conventions of a thriller.

Damsel in distress: The character is hanging of the edge of a gutter of a building, he relies on another character (hero).

Protagonist: the flawed hero, the character is scared of heights. this is shown as he is hanging of the building and is made worse when he see's the police officer fall to his death when trying to help him.

Lighting:Shadows cast over woman's face in beginning. The lighting then turns red, symbolize; lust, danger, blood. In rooftop scene, grey colours used, dull, pathetic fallacy = weather reflects the mood (cloudy, grey).

Fear of the unknown= Don't see entire face of woman, unaware of who she is. Her eye's widen in shock, it's unknown why. Unknown why man is running from the police.

At the beginning when the animated patterns come up on the woman's eye could represent a kind of hypnosis which connotes the control she has over the victim or vice-versa. This links in with obsession and gives the audience the impression that the villian could be obsessed with the 'damsel in distress'.

Music is used throughout to add tension, suspence and to keep in time with the dull, tense mood.
