Structure of a Thriller Opening

A Narrative Opening:

The story begins immediately, and the credits appear over the top of the action throughout. Narrative can be anything from setting the scene to a phone conversation.

A Discrete Title Sequence:

The opening credits appear separate from the rest of the film often in their own specially edited sequence.

Titles Over a Black Screen:

The opening credits appear before any action starts and is often followed by the narrative. 

        

Stylized Editing:

The opening credits are edited in a very stylized way, incorporated somehow into the action. They are most likely accompanied by upbeat or fast paced music.
