Well, honey! Women in film means that sometimes there aren't enough girls in the movies you watch. The people in charge, like the director and producer and screenwriter, are usually men and sometimes they forget to put in enough female characters. This can make girls and women feel left out, like they don't matter as much as boys and men.
But, there are some amazing women who are trying to change this! They are working hard to make sure that the movies you see have more girls and women in important roles. They want to show that girls can be strong and brave, just like in real life. They also want to show that girls can be anything they want to be, like doctors or astronauts or even superheroes!
So, don't worry, sweetie! There are lots of grown-ups who are fighting to make sure that girls and women are included in movies and TV shows, and they won't stop until it's as easy to find female characters as it is to find male ones.
