A look into opening sequences:

This opening sequence is from a film called catch me if you can. When watching any opening sequences there are specific parts which are included:

• Film title
• titles
• setting the tone of the film    

an opening sequence of a film often sets the genre of the film to the audience. For an example a horror film would set the mood of the film to be a horror film not a comedy. With 'catch me if you can' the entire story is explained in the opening sequence, however for some one watching the film for the first time, there isn't enough information for them to truly understand the details but it is at the same time intriguing and makes the viewer want to watch the rest of the film.
