Which aspect is typically included in a treatment for a film project?

In the context of developing a film project, including character details in a treatment is essential because it provides a foundational overview of the characters that drive the story. This aspect outlines their backgrounds, motivations, and relationships, which are crucial for anyone reading the treatment to understand the narrative's depth and emotional resonance. Character details help to establish connections with the audience and offer insight into how the characters will evolve throughout the story. By detailing who the characters are and what they want, writers set the stage for the dramatic arcs and themes that will be explored.

Other aspects such as shot lists, budget estimates, and marketing strategies, while important in the overall filmmaking process, are typically not included in a treatment. The treatment is mainly focused on the narrative and its elements, rather than production logistics or promotional planning.
