The structure of Thriller openings

I looked at a few clips and analysed the three basic structure. These 3 basic structures are part and is what makes the opening of a film. These are :

- Narrative opening with the titles running throughout
- A discrete tite sequence
- Titles over a blank screen, followed by the narrative opening

I analysed the opening of  'The taking of Pelham 123'

 Narrative opening

- Its got the title sequence runing thourgh the narrative opening
- Establishing shots with the production companies name

Discrete title sequence

- It doesnt really have a seperate title sequence, however its title sequence is roling during the opening scene. 

 Titles over blank screen

- Its got a black background 

- Title with the fonts, Sans Serif fonts
