"If you're first page doesn't give you a hard-on, you should throw the damn thing away."

- Sam Fuller

We watched a documentary about title sequences in class. Through it, we learnt the following:

In your title sequence, it is important not to give everything away in the first five minutes. Alternatively, if you make your sequence too long and complicated, there's a risk that you'll never answer the questions established in it. The sequence must give some details to start the story but not give everything away for fear of losing suspense.

The title sequence from Se7en Told a story, introduced you to the obsessive nature of the protagonist, and foreshadowed the events of the film.

For the opening for his movie, A Touch of Evil, Orson Welles wanted to plunge the audience into his story without giving them time to prepare themselves. They put a score and credits onto the sequence because they did not understand what Welles was trying to achieve, much to his disappointment. Showing the end at the beginning of the film is a common trait of film noir.
