There is a range of different types of Movie Title Design Sequences, Opening Credits, and Intros that filmmakers and directors use in their projects. Each one has its own distinct reason for existence and the role that it plays in storytelling beyond just showcasing the credit. The art of the title sequence is really a lot of detective work figuring out the themes of the story and putting that into a framework or motif of imagery that makes sense and adds to the narrative without giving too much away.
