Maleficent became an instant hit with audiences around the world when she first appeared in cinemas five years ago, with her sculpted cheekbones and twisted devil horns.

A vengeful fairy curses an infant princess, only to discover that the child may be the one person who can restore peace to their troubled land.

What are their personalities like?
 

2. What’s the theme of the film?
The film’s main theme is inclusiveness and cooperation between different people. Both fairies and humans must learn to understand each other if they want to protect the land where magical creatures live together.

3. What are some comments about the film?
Maleficent (2019) is a fierce fairy tale about the joy of being uniquely individual. These characters are so unique that you would remember even many years after you finished watching the movie.
                                                    --Carla Renata
The film is about kindness and acceptance and tolerance. We want people to be kind to one another ... to understand that it is wrong to exile people that are different.
                                                    --Fanning

Further thinking
Do you know other films with similar themes of acceptance and tolerance?

 


What is acceptance?
Acceptance is the ability to see that others have a right to be their own unique persons. That means having a right to their own feelings, thoughts and opinions. When you accept people for who they are, you let go of your desire to change them. You let them feel the way they want to feel, you let them be different and think differently from you. Everyone is different in one way or another.
