Green Screen is a filming technique where actors perform in front of a bright green background, which can later be replaced with any scene or special effects during editing. It's also known as "chroma key" or "chromakey." This is like having a magical backdrop that can be changed to anything - from exotic locations to fantasy worlds. Film crews use this method to create scenes that would be too expensive, dangerous, or impossible to film in real life. Think of it as a blank canvas that allows filmmakers to add whatever background they want after filming.
