For decades, film and TV productions have used green and blue screens to place actors into new environments. Now, LED walls are revolutionizing this process by projecting 3D environments in real time behind actors to provide the illusion of being in a physical location. These methods were put to the test on Disney’s "The Mandalorian," of which over half was filmed indoors on a virtual set. This process of combining traditional cinematography techniques with advanced world-building technology effectively eliminates the need for a green screen.
