What is the definition of a principal character in a film?

A principal character in a film is defined as a significant character involved in more than one scene. This character typically drives the narrative forward, plays a crucial role in the development of the plot, and often has a well-defined arc. Principal characters are frequently central to the film's themes and emotional impact, making their presence vital throughout various key moments of the story.

In contrast, the other options refer to characters that do not possess the same level of significance. Minor characters, such as those with little screen time or only seen in one scene, contribute to the storyline but do not have a predominant role in shaping it. Additionally, a character without dialogue may serve a visual purpose but lacks the depth and interaction that define a principal character's involvement in the narrative. Understanding the distinction between these roles is essential for analyzing character dynamics within film production.
