Supporting characters in movies are really important, even if they're often ignored. They help the audience understand the main character better.

First, these characters reflect what the main character is like. They can show similar traits or act very differently. This helps viewers see the journey of the main character, including what drives them and how they feel.

Second, supporting characters often have their own stories, called subplots. These subplots connect back to the main story. They can show more about the main character's challenges and victories. For example, a wise mentor can symbolize hope and guidance, while a villain might show the main character's personal struggles. This mix of stories makes the experience richer and helps the audience feel more empathy.

Also, supporting characters can add humor and relief during tense moments. Their funny behaviors and interactions provide a break from suspense, making it easier for viewers to handle strong emotions. Beyond just being entertaining, these characters help build a sense of friendship and belonging. Viewers may see parts of themselves in these characters, which makes them connect more deeply with the film.

In short, supporting characters play important psychological roles. They reflect, enhance, and entertain. They help audiences explore complex feelings and relationships, which leads to a deeper understanding of the movie's message. By doing all this, they make the viewer's experience better, ensuring that the film stays in their minds even after it ends.
