Screenwriting is the art of crafting scripts for films, television shows, and other visual media. A screenwriter creates the dialogue, characters, and plot, transforming ideas into a structured format that guides directors and actors. The script serves as a blueprint, detailing each scene and action, ensuring that the story unfolds effectively on screen. In screenwriting, understanding the three-act structure is essential. This framework divides the story into three parts: setup, confrontation, and resolution. By following this structure, screenwriters like Christopher Nolan or Greta Gerwig can build engaging narratives that captivate audiences and convey emotions through their characters and story arcs.
