There are usually two parts to a film. Macro elements, big parts of a film, and Micro elements, small parts of a film. The big parts of the film are called genre and narrative. Genre is the type of film. There are many different genres in the film industry, such as horror, comedy, sci-fi, thriller, action, romantic comedy, animation, musical, and indie.
Narrative is the sequence of the film. There are two types of narratives, linear and non-linear. Linear is when the sequence of events are shown in the order that they took place, the beginning, middle, and end. It is the most common form of narrative structure. Non-linear is when the sequence of events are shown out of the expected order.
