Okay kiddo, have you ever watched a movie and noticed that some things in it have a deeper meaning? Maybe the color of the clothes the characters wear, or the objects that are placed in certain scenes. Well, that's just what semiotics is all about - it's like a secret code hidden in a movie that helps people really understand what's happening.
You know how you use words to communicate, like saying "I'm hungry" when you want a snack? Well, movies use pictures and symbols to communicate too, and that's called semiotics. For example, if you see a character in a movie wearing all black, that might mean they are evil or dangerous. If you see a scene with a lot of red, that might mean the scene is supposed to be intense or emotional.
Semiotics is like a secret language that filmmakers use to make their movies more interesting and to help tell their story. And if you're paying attention, you can crack the code and really understand all the hidden messages in a movie!
