Opening Sequences are Important

In the first two minutes of a film, conventionally, the main characters/actors can be introduced, through appearance or credit. The films opening can have a good effect, by using generic conventions to help the audience establish the type of film it will be and also build up expectations of the plot-line. If the opening sequence is engaging and connecting to the audience, then they are going to enjoy the film and perhaps going to see it again/purchase the DVD or any other merchandise - working as a marketing machine for the franchise. There are some very memorable, effective opening opening sequences - for example, every Star Wars film begins with the suspended space writing and then getting straight into the action.
