Film clip analysis- North bt Northwest

Colours and design (background)
Very bold distinct colours are used, the white text stands out against the green patterned background. The main actors name Carey Grant is in a big font, to automatically get the spectator's attention. (films with a famous and well known actors sell well).
Music
The sound track for the opening of the film was produced by Bernard Herrmann. It is very instrumental, as you can hear a very high pitched, squeaky and jumpy sound produced by violins. There is a build up because the music gets quicker and louder and this kind of emphasizes the theme of the story and the suspense of it all, as the narrative theme is 'innocent on the run' This theme is replicated in the music.
Brief summary
Roger Thornhill is the protagonist and VanDam and his gang are the antagonists. Thornhill is a victim of a mistake in identity which causes disruption and leads to a series of events, causing our protagonist to be on the run from the police and VanDam and his men.
