Characters in movies change a lot to show important ideas in society. This helps people connect more with the story.

Here are some examples of how characters evolve:

1. Social Movements:

   • In the movie "12 Years a Slave," we see Solomon Northup's tough journey from being free to being a slave. His story shows the harsh reality of slavery and the fight against unfair treatment in history.

2. Gender Identity:

   • The film “The Danish Girl” tells the story of Lili Elbe. Her experience shows how our understanding of gender has changed. It also highlights how society is starting to accept different identities as she transitions and challenges traditional ideas.

3. Technology and Isolation:

   • In "Her," the main character, Theodore Twombly, faces feelings of loneliness because of technology. His relationship with an AI shows how love and connections are complicated in our digital world.

These character journeys do more than just entertain us. They make us think about important issues in our society, showing us how character development is key to delivering deeper messages.
