A movie ranch is sort of like a big outdoor playground for people who want to make movies or TV shows. Instead of being a real town or city that people live in, a movie ranch is a pretend place that looks like a town or city. It usually has buildings like stores, houses, and maybe even a hotel or a church!
People who make movies or TV shows use movie ranches to film scenes when they can't actually film in a real town or city. Maybe they can't go to a real city because it costs too much money, or the city is too busy and crowded to film in. By using a movie ranch, movie makers can create any kind of pretend town they want and have more control over the filming. They can change the look of the buildings, move things around, and even make it look like a different time period, like the old west!
So, just like how you might play pretend with toy cars and houses, movie makers play pretend with big, real buildings by using a movie ranch.
