The document discusses the differences in approach between the filmmaker's preliminary task and main film opening task. For the preliminary task, there was little planning, research, or attention to conventions. However, for the film opening the filmmaker learned from this experience. They placed a strong emphasis on planning, research, evaluating other films, finding suitable locations and actors, selecting an appropriate soundtrack, and considering lighting and other technical elements. This extensive preparation led to a higher quality final product that better followed film genre conventions.
