The document discusses characterisation in films. It defines characterisation as how a film reveals the personality of characters, which can be done directly by telling the audience or indirectly by showing things that reveal personality through speech, thoughts, effects on others, actions, and looks. Examples are provided from films like Se7en and Mean Girls to illustrate indirect and direct characterisation. The document also discusses how protagonists and antagonists are characterized at the beginning of films to establish them as the "good guy" or "bad guy."
