WHAT IS THE PURPOSE OF A TITLE SEQUENCE AND FILM OPENER?
Purpose of a title sequence:
The purpose of a title sequence is to inform the audience about how a film is made or what's it about. Usually, the names of the director, producer, music producer etc are presented at the beginning of the film, so that the audience are aware of whose work it is and also, so that the directors and producers can have the satisfaction, knowing that they are achieving credit for their work. As well as telling us who produces and directs it, we are also introduced to the main characters, the location and genre. However, in some films, the characters are not introduced immediately to build tension and make the film seem more intense just like the introduction of the film "The Girl With The Dragon Tattoo".
Purpose of a film opener:
Moreover, the purpose of the opening on the film is the same to the purpose of a title sequence because it is what hooks the audience in and gets them eager to know what is going to happen next. It gives the audience an idea or clues about what the plot is but at the same time, doesn't give too much away in order to make an implication that there are more interesting parts coming up later. As Thomas Sutcliffe says, "Films need to seduce their audience into long term commitment." The opening of the film is also important because the audience's feelings or the crave to watch the film or not depends on the film opener. If there is not much going on, the audience may get bored and not bother watching and if there giving away too much, the audience may think there is no reason to watch it if they already know what's going to happen. So, in order to avoid that, there should be a balance between having a bit of mystery as well as clues.
Example: This is the video from the introduction of the film "The Girl With The Dragon Tattoo" and this introduction has no talking or clear characters shown, just music. This is to maintain it's mystery and to make it more interesting, almost challenging the audience to watch it all. The atmosphere is also very dark and mostly of ink and dragons which helps to give the audience an idea of what genre it could be.
