Okay, imagine you love to play pretend with your friends and come up with really cool stories to act out. Now imagine that there are grown-ups who do that too, but they make movies out of their stories that you can watch on a big screen.
One of the grown-ups who makes these movies is named Steven Spielberg. He has a big imagination and is really good at making movies that make people feel things like happy, scared, or excited.
He started making movies when he was still a young grown-up, but his first big hit was a movie called Jaws about a big, scary shark that terrorizes a beach community. It made lots of people afraid to go swimming in the ocean for a while!
After that, Steven Spielberg made many more movies that people love, like E.T. about a little alien who befriends a boy, and Jurassic Park about dinosaurs that come back to life. He even made a movie about a special horse named Joey called War Horse.
Now, Steven Spielberg is a really famous movie maker and people love to watch his movies because they are exciting, funny, and sometimes even a little bit scary.
